Description
Technical field
The present invention relates to a kind of alkaline earth phosphate purple and blue long afterflow luminescent material and preparation method, belong to the luminescent material technical field.
Background technology
Long after glow luminous material claims noctilucent material again, and it is that a class absorbs the light that sunlight or source of artificial light produced, and sends visible light, and still can continue luminous material after stopping exciting.Having the daylight of utilization or light storage light, night or in the luminous characteristics in dark place is a kind of energy storage, energy-conservation luminescent material.Long-afterglow material application aspect low light level illumination, demonstration is very extensive, and its product such as luminous template, luminous paint, luminous printing ink, luminescent plastics, luminescent ceramic, luminous chemical fibre, luminous safety notice etc. are used for industry-by-industries such as communications and transportation, fire-fighting emergent safety, national defense and military, textiles and finishing material in a large number.
The development of long-afterglow material has very long history, people's research early be the sulfide long-afterglow material, as alkaline earth zinc sulphide etc.But there is significant disadvantages in this material, supports as after-glow brightness, and time of persistence is short, poor chemical stability, easy deliquescence etc.Can be by adding radioelement.Means such as material coated overcome these shortcomings; But the adding of radioelement all works the mischief to HUMAN HEALTH and environment, and the use of this material is subjected to very big restriction.

3+(1996 the 143rd volume 2670-2673 pages or leaves of J.Electrochem.Soc.), after UV-light or day optical excitation, the persistent green long afterglow of energy emitting bright, its after-glow brightness height, the time is long, and materials chemistry stability is all considerably beyond the sulfide long-afterglow material.
In recent years, be that the long-afterglow material of matrix also successively has been in the news with silicate.The silicate long-afterglow material is disclosed as patent CN98105870.6 and CN200380801922.6.This long-afterglow material has superior stability, but after-glow brightness and time are no more than aluminate long afterglow materials.
The report that with phosphoric acid salt is the long-afterglow material of matrix is seldom.Chinese patent CN03109879.7 has reported a kind of zinc phosphate long after glow luminous material and preparation method thereof.The selected substrate material of this invention is the zinc phosphate of different chemical structures.Different phase structures makes long-afterglow material present distinct colors, and yellow-green colour, orange-yellow and red three kinds of colors are arranged.
Summary of the invention
The invention provides a kind of alkaline earth phosphate long afterglow luminous material and preparation method.The invention provides a new steady persistence substrate material, and, can regulate the afterglow color by selecting different alkaline earth ions.
The selected substrate material of the present invention is a mixed alkaline earth cationic phosphoramidate hydrochlorate.Main active ions are europium ions.Auxiliary activator ion is one or more the lower valency and the metal ion of high valence state.After the matrix absorption part energy, a part can shift and be caught by auxiliary activator, subsequently, under thermal excitation, gives the dominant activator ion in the slow release of room temperature and with transmission ofenergy.At last, by europium ion emission twilight sunset.By the kind of alkaline earth cation in the control matrix, this system can be launched purple light or blue light.
A kind of alkaline earth phosphate long afterglow luminous material of the present invention, it can be with following chemical formulation:
R
(1-x-y±m)M
2±m(PO

2:xEu，yN
In the formula: R is a kind of alkaline earth cation Ca, Sr or Ba, M is alkaline earth cation Mg, and N is one or more positively charged ions among Sc, Y, La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Al, Ga, In, Si, Ge, Sn, Sb, Bi, Ti and the Zr; X, y refer to the molar fraction of corresponding dopant ion, x=0.001-0.2, y=0-0.2.M is a Mg ionic molar fraction excessive or in shortage, m=0-0.1.
A kind of preparation method of alkaline earth phosphate long afterglow luminous material is as follows: the carbonate, oxide compound, the phosphatic raw materials that take by weighing respective element in aforesaid composition and ratio, after its grinding and mixing, directly in 950-1200 ℃ of sintering 5-12h or at 300-600 ℃ of pre-burning 3-6h, be cooled to room temperature, behind the regrinding, in reducing atmosphere,, make the purpose compound in 950-1200 ℃ of sintering 5-12h.
Preparation method of the present invention is simple, and the long-afterglow material that makes can present purple light or blue light distinct colors, and twilight sunset is bright, sustainable at least 5 hours of time of persistence.Can excite with daylight; Simultaneously, this long-afterglow material preparation technology's production cost is low, and product chemistry stable in properties is "dead", can not work the mischief to human and environment.Long after glow luminous material of the present invention application aspect low light level illumination, demonstration is very extensive, and its product such as luminous template, luminous paint, luminous printing ink, luminescent plastics, luminescent ceramic, luminous chemical fibre, luminous safety notice etc. can be used for industry-by-industries such as communications and transportation, fire-fighting emergent safety, national defense and military, textiles and finishing material in a large number.
