摘要
在还原气氛下采用高温固相法制备了BaZrO3∶0.05Bi,xEu(x=0,0.010,0.025,0.050)荧光粉,并研究了其发光性能。研究证实:Bi,Eu共掺杂的BaZrO3荧光粉在近紫外340nm激发下,具有来自于Bi 3+的宽带发射峰和Eu3+的特征发射;Bi 3+对Eu3+具有能量传递和敏化作用,通过Bi 3+和Eu3+之间的能量传递获得了具有白色发光的BaZrO3荧光粉。
The BaZrO3∶0.05Bi,xEu（x=0,0.010,0.025,0.050） phosphors were prepared by using high-temperature solid-state reaction in reducing atmosphere,and their photoluminescence properties were investigated.The broadband emission peak of Bi3＋ and the typical emission peaks of Eu3＋ were observed in the BaZrO3 phosphors co-doped with Bi3＋ and Eu3＋ under 340 nm excitation.It is confirmed that energy transfer occurred between Bi3＋ and Eu3＋ in the BaZrO3∶Bi,Eu phosphors,and the white light BaZrO3 phosphors can be obtained through the energy transfer between Bi3＋ and Eu3＋.
