Description
Technical field
The contents of the present invention are a kind of for growing SrMoO4Crystal or active ions adulterate SrMoO4The side of crystal
Method is related to technical field of optoelectronic functional materials, more particularly, to preparing a kind of work that can be used as solid optically functional device
The artificial lens technical field of medium.
Background technique
Molybdate crystal due to having high density, good thermostabilization and irradiation stability, ideal flashing efficiency,
Make they photo-luminescent devices, solid-state laser, optical fiber, in terms of application it is more.
Alkali earth molybdates ReMoO4(Re=Mg, Sr) is a kind of important optical crystal matrix.SrMoO4It is the system
In important a member, it belongs to tetragonal crystal system, space group I41/ a, cell parameter are as follows: a=5.3897, c=12.0209
, z=4.In the crystal, Sr atom is eight-coordinate, and Mo atom is four-coordination.Every 6 SrO8Polyhedron is by sharing Sr-O
Polyhedral a line and form a Sr6O42Group connects each other together, SrMoO4Crystalline framework can regard this as
A little Sr6O42The cage structure that group is formed by connecting by way of sharing oxygen atom, MoO4Tetrahedron is filled in these caged
The gap of structure.
SrMoO4For congruent melting compound, melt temperature is 1460 DEG C.The crystal can be prepared by czochralski method,
Researcher is prepared for SrMoO using czochralski method4And it is doped with Tm3+、Ho3+、Yb3+、Er3+And Pr3+Equal active ions
SrMoO4Crystal.Meanwhile Chinese patent CN200810070582.5, CN200810070576.X, CN200810070568.5 points
Preparation doping Nd is not disclosed3+、Yb3+And Tm3+The SrMoO of ion4The preparation method of monocrystalline, what they were used is all czochralski method.
The melting point compound is higher, and the MoO in raw material3Saturated vapor pressure is lower, volatile so as to cause raw material deviation at high temperature
Standard stoichiometry ratio, so the SrMoO usually come out using Czochralski grown4Monocrystalline optical quality is to be improved.Therefore, existing
Some preparation SrMoO4There are the solutions of following two problems demand in the method for monocrystalline: 1, growth temperature is high；2, melt is in high temperature
Lower volatilization is serious.To solve above-mentioned two problems, Chinese patent CN200710009975.0 discloses a kind of improved czochralski method
For growing SrMoO4Monocrystalline.In the improved czochralski method, author introduces NaMoO4As fluxing agent, by SrMoO4Monocrystalline
Growth temperature is reduced to 1200 DEG C.But the growth temperature of the crystal is not still effectively reduced in this improved czochralski method,
NaMoO simultaneously4Addition there is no Essential Action to melt system volatility at high temperature is reduced.
Utilize K2MoO4SrMoO can be prepared as fluxing agent4Monocrystalline uses K2MoO4As fluxing agent and control its
Content in melt can also reduce SrMoO4The growth temperature of monocrystalline.But in whole system all it is in the molten state molybdenum
Hydrochlorate, the volatility of system are still very serious.
Summary of the invention
To solve SrMoO4The growth temperature height and melt faced in the existing preparation method of monocrystalline volatilizees seriously at high temperature
The problem of, the invention adopts the following technical scheme:
One kind is for growing SrMoO4The preparation method of crystal, which uses top seed crystal flux growth metrhod preparation, used
Fluxing agent is Na 2MoO4+B2O3Or K2MoO4+B2O3Composite fluxing agent.In above two composite fluxing agent system, Na2MoO4
Or K2MoO4With B2O3Ratio be 4:1(molar ratio).When with SrMoO4-Na2MoO4-B2O3System grows SrMoO4Crystal
When, solute SrMoO4Concentration be 25%-10%(molar ratio), crystal growth temperature section is 990 DEG C -880 DEG C, and rate of temperature fall is
0.5-5 DEG C/day, brilliant rotational speed rate is 5-60rpm；When with SrMoO4-K2MoO4-B2O3System grows SrMoO4When crystal, solute
SrMoO4Concentration be 25%-10%(molar ratio), crystal growth temperature section be 1050 DEG C -850 DEG C, rate of temperature fall 0.5-5
DEG C/day, brilliant rotational speed rate are 5-60rpm；
The SrMoO prepared using the technical method4Crystal, crystal parameters are as follows: tetragonal crystal system, space group
For I41/ a, cell parameter are as follows: a=5.3897, c=12.0209, z=4；
SrMoO is prepared using the technical method4When crystal, it can according to need and adulterate active ions thereto, such as Tm3+、
Ho3+、Yb3+、Er3+And Pr3+Ion etc., the Sr in these active ions replacement lattices2+, to prepare active ions doping
SrMoO4Crystal, wherein the doping of active ions is 1-10 at.%；
In above-mentioned technical method, SrMoO4Raw material be SrCO3And MoO3, K2MoO4Raw material be K2CO3And MoO3,
Na2MoO4Raw material be Na2CO3And MoO3, B2O3Then derive from H3BO3.At high temperature, above-mentioned raw materials are according to following chemical equation
Formula is reacted:
Na2CO3+MoO3= Na2MoO4+CO2↑
K2CO3+MoO3= K2MoO4+CO2↑
SrCO3+MoO3=SrMoO4 +CO2↑
2H3BO3=3H2O↑+B2O3
In the above preparation method, B2O3Introducing be necessary. B2O3Introducing can effectively improve melt system
Viscosity reduces the volatilization of melt system and entire melt is made to become thoroughly bright, is very beneficial for the molten of stable crystal growth
Body environment.In order to illustrate B2O3Introducing be able to suppress the volatility of melt system, we devise one group of comparative test: we
Choose SrMoO4-Na2MoO4-B2O3And SrMoO4-Na2MoO4System carries out thermogravimetric analysis, and raw materials used is AR grades of SrCO3、
Na2CO3、MoO3And H3BO3, the model SDT Q600 V8.2 Build 100 of thermogravimetric analyzer.SrMoO4-Na2MoO4-B2O3
System according to three 1:1:1 molar ratio ingredient 15mg, SrMoO4-Na2MoO4System according to the two 1:1 molar ratio ingredient
15mg.It tests two systems and rises to the variation of 900 DEG C of system gross masses with the raised relationship of temperature, heating rate 10 from room temperature
DEG C/minute, 100 minutes are kept the temperature at 900 DEG C.Test result is as depicted in figs. 1 and 2.
As shown in Figure 1, two fluxing agent systems are before 500 DEG C with the H in raw material2O、H3BO3、SrCO3And Na2CO3
Participation physical-chemical reaction decompose, the quality of system will appear several places and die-offs or reduce in ladder shape.Specifically,
SrMoO4-Na2MoO4Have in system raw material and holds evaporable H2The O and SrCO for being easy reaction decomposition3And Na2CO3, in temperature-rise period
In have following variation: from room temperature to 71 DEG C, since the evaporation system TG of water has dropped to 96% from 100%；From 71 DEG C to 330 DEG C,
Due to Na2CO3With MoO3It reacts, generates CO2, along with dehydration is continued, system TG is down to 84%；It is warming up to from 482 DEG C
490 DEG C, due to SrCO3With MoO3It reacts, generates CO2, system gross mass accounts for material quality and becomes 82.8% from 83%.
And the SrMoO before 500 DEG C4-Na2MoO4-B2O3System is from 71 DEG C to 330 DEG C in addition to there is Na2CO3With
MoO3It reacts and generates CO2Except, there are also H3BO3The process of dehydration.Two individuals tie up to gross mass base between 500 DEG C to 800 DEG C
Originally it remains unchanged.After 800 DEG C, as the temperature rises, SrMoO4-Na2MoO4-B2O3Gross mass it is nearly constant constant, and
SrMoO4-Na2MoO4The gross mass of system is then also decreasing.
Fig. 2 is SrMoO4-Na2MoO4-B2O3And SrMoO4-Na2MoO4The thermogravimetric of holding stage after system is warming up to 900 DEG C
Analysis, constant in system is SrMoO in 900 DEG C of holdings 100 minutes4-Na2MoO4-B2O3System gross mass is down to by 100%
98.6%, and SrMoO4-Na2MoO4System gross mass is down to 97.4% by 100%, due to B2O3Presence and reduce system melt
Volatilization.The results show of Fig. 1 and Fig. 2, B2O3Apparent inhibiting effect can be played to the volatility of system.
By SrMoO4Crystal or the SrMoO of active ions doping4The Solid-state Optics device system that crystal is used to prepare,
The Solid-state Optics device system can be used for particle detection, laser device, spectroscopy device, biomedicine or military field.
Beneficial effects of the present invention
Preparation SrMoO of the present invention4Crystal technology method, can be by SrMoO4The growth temperature of crystal reduces, together
When the volatility of melt system during the growth process, the growing environment of stable crystal can also be effectively reduced.
