制备了铕激活的钇、锆、钆的正烯酸盐、钒酸盐。砷酸盐、铌酸盐等萤光粉以及混合阴离子的螯光粉。铕发射的红谱线及橙谱线的强度比值,是和铕离子近邻的微小变化紧密相关的。一些未加激活剂的萤光粉有兰色强发射,而在加入Eu激活剂后,观察到能量向Eu传送。这种传送的效率远远高于(钅忒)激活的这些萤光粉。铌酸粉及混合铌酸——磷酸盐的激发谱,较磷酸物延伸到更长得多的长波光谱区。YV_(1-x)P_xO_4:Eu萤光粉的量子效率达至约70%,大部分萤光秒,在高温时都比在室温时更亮。混合的钇磷俊—钒酸盐萤光粉的淬灭温度高于单一的YVO_4:Eu萤光粉。
Eu-activated yttrium, zirconium, and gadolinium orthoacids and vanadates were prepared. Arsenate, niobate and other phosphors and a mixed anion chelating powder. The intensity ratio of the red line and the orange line emitted by europium is closely related to the small change of the neighbor of europium ion. Some non-activator-based phosphors have strong blue emission, and after the addition of Eu activator, energy transfer to Eu was observed. The efficiency of this transfer is much higher than those activated by (Intuit) phosphor. The excitation spectra of niobate powder and mixed niobic acid-phosphate extend much longer wavelength spectrum than phosphate. The quantum efficiency of YV_ (1-x) P_xO_4: Eu phosphor reaches about 70%, most of the fluorescence seconds are higher than at room temperature. The quenching temperature of mixed yttrium phosphate-vanadate phosphor is higher than that of single YVO_4: Eu phosphor.
