本研究以固態反應法合成NaNbO3:Er3+及LiNbO3:Er3+,探討其於383 nm左右波長UV光激發光源下,Er3+摻雜濃度、主體變化、燒結條件對合成螢光體之晶體結構、粒徑大小及螢光體發光特性之影響。
以固態反應法合成之NaNbO3:Er3+及LiNbO3:Er3+螢光體於383 nm左右之激發光源,皆有放射綠光的現象 ( 520 nm ~ 570 nm )。主體的改變造成激發光譜和放射光譜的變化。NaNbO3:Er3+其548.3 nm放射強度 (λex = 384 nm )與LiNbO3:Er3+其551.2 nm放射強度(λex = 384.7 nm )是隨燒結溫度之增加而增加,亦隨Er3+ ( 0.3 ~ 5 mol% )摻雜濃度之增加而增加,分別在3 mole% 與0.5 mole% 摻雜時有最大放射強度。
NaNbO3:Er3+ and LiNbO3:Er3+ phosphors were synthesized by solid state method. Effects of the contents of Er2O3, variation of host and sintering temperature on the phosphors crystallization, particle size, shape and photoluminescence properties were investigated.
NaNbO3:Er3+ and LiNbO3:Er3+ phosphors both show emission behavior of green light ( 520 nm ~ 570 nm ) under excitation source about 383 nm UV light. The variation of hosts alters the excitation and emission spectrum. The emission intensity of NaNbO3:Er3+ ( at 548.3 nm , λex = 384 nm ) and LiNbO3:Er3+ ( at 551.2 nm , λex = 384.7 nm ) increases with sintering temperature and Er3+ dopants. The results show the strongest emission intensity occurs when doping 3 mol% and 0.5 mol% Er3+, respectively.
