简述灯用荧光粉近年来国内外发展动态和主要成果。评述为减少汞吸附 ,降低汞耗而对卤粉和三基色粉进行的各种包膜试验。结果表明 ,包比不包好 ;包稀土氧化物 ,特别是包 L a2 O3 ,比包 Al2 O3 好。着重介绍新型红、蓝、绿三基色粉的特点。简要描述对 Eu2 +和 RE3 +激活的碱土金属单铝酸盐的长余辉发光过程所建立的各种模型 ,和含氧酸盐量子劈裂材料的机理。提出今后的课题
A brief account of domestic and international developments and major achievements of fluorescent phosphors for lamps in recent years. Comment on various envelope tests on halogen and tri-base toner to reduce mercury adsorption and reduce mercury consumption. The results show that the package is not wrapped better than the package Al 2 O 3. Focus on the introduction of the new red, blue and green three-color toner characteristics. A brief description of various models established for the long afterglow luminescence of Eu2 + and RE3 + activated alkaline earth metal monoaluminates and the mechanism of oxygenated salt quantum splitting materials are briefly described. Put forward the future issue
