Abstract

도너농도가 제한되기 위하여 발광효율이 높고 첨가원소의 선택에 의해 전자선 여기에 의해 각종 발광색을 실현할 수 있고, 수명특성에도 우수한 형광체를 제공한다.In order to limit the donor concentration, the luminous efficiency is high, and various emission colors can be realized by electron beam excitation by selection of additional elements, thereby providing a phosphor having excellent life characteristics.

Ga2S3을 23.5g(0.1mol)에 MgCl2를 0.02g(0.1mol%/Ga)가한다. 다시, Si농도와 Mg농도가 같아지도록 폴리실라잔 20% 용액을 0.05g 가한다. 혼합하여 암모니아 분위기 1100℃에서 10시간 유지하고, GaN : Mg, Si형광체를 얻는다. 폴리실라잔의 양을 변화시켜서 Si량을 0.001mol∼10mol%까지 변화시켜서 복수종류의 시료를 얻는다. Si 없는 시료와 폴리실라잔 대신 SiO를 사용한 시료도 제작하였다. 이들 시료를 형광표시관 양극에 사용하고, 점등하여 형광체 휘도특성을 평가하였다. 각 시료의 발광색은 모두 청색이었다. 발광휘도는 Si의 도프량이 적은 영역에서는 휘도가 낮고, 과다하면 휘도가 낮아진다. Mg의 농도 M은 0.01〈M〈0.3이 좋고, Si의 농도 X는 0.005〈X〈0.3이 좋다.23.5 g (0.1 mol) of Ga 2 S 3 is added and 0.02 g (0.1 mol% / Ga) of MgCl 2 . Again, 0.05 g of polysilazane 20% solution is added so that the Si and Mg concentrations are equal. The mixture was kept at 1100 ° C. for 10 hours in an ammonia atmosphere to obtain GaN: Mg and Si phosphors. By varying the amount of polysilazane, the amount of Si is varied from 0.001 mol to 10 mol% to obtain a plurality of types of samples. Samples without Si and samples using SiO instead of polysilazane were also prepared. These samples were used for the anode of the fluorescent display tube and lit to evaluate the phosphor luminance characteristics. The emission color of each sample was all blue. The luminance of light emitted is low in the region where the doping amount of Si is low, and the brightness is low when excessive. As for the concentration M of Mg, 0.01 <M <0.3 is good and the concentration X of Si is 0.005 <X <0.3.
