本文介绍了稀土飞点扫描荧光粉,提出了铈激活钇铝镓石榴石的制备工艺。研究了镓取代对峰值的影响。证明镓取代可使峰值向短波长方向移动。以镓取代2个铝时,即发绿光的 PYG 飞点扫描荧光粉发射强度最大。试验对粉的粒度、晶体结构进行了测定,并制成高分辨率飞点管测试了亮度和耐灼伤性能。在实际应用中得出管的寿命及有关数据。PYG 荧光粉经用户使用鉴定取得满意结果。
In this paper, rare earth fly-spot scanning phosphor is introduced and the preparation of cerium-activated yttrium aluminum gallium garnet is proposed. The effects of gallium substitution on the peak were studied. It is proved that gallium substitution can shift the peak to short wavelength. Substituting gallium for two aluminum, the green-emitting PYG flying spot scanning phosphor has the highest emission intensity. Test on the particle size of the powder, the crystal structure was measured and made of high-resolution fly-point test brightness and burn resistance. The practical application of the tube life expectancy and related data. PYG phosphor identified by the user to obtain satisfactory results.
