| 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340 nm 激发下，具有来自于Bi3+的宽带发射峰和Eu3+的特征发射;Bi3+对Eu3+具有能量传递和敏化作用，通过Bi3+和Eu3+之间的能量传递获得了具有白色发光的BaZrO3荧光粉。

| Abstract: | 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+. |
