采用溶胶-凝胶燃烧法成功合成了未掺杂和Eu3+激活的Bi3TiNbO9(BTNO)纳米荧光粉。研究了热退火对 BTNO 颗粒的相结构和结晶度、形貌和紫外可见吸收的影响。光致发光（PL）特性表明，BTNO 纳米粒子检测到宽广的蓝色发射，并且在掺杂样品中观察到特征性的 Eu3+ion5D0→7FJ(J=1, 2, 3, 4) 跃迁。进一步的研究表明，Eu3+离子在赝钙钛矿层的A位点取代了Bi3+离子。从高亮度的荧光图像和短的衰减时间可以证实这种新型橙红色荧光粉在发光器件中具有潜在的应用。
Undoped and Eu3+-activated Bi3TiNbO9(BTNO) nanophosphors have been successfully synthesized by sol–gel combustion method. The effects of thermal annealing on the phase structure and crystallinity, morphology and UV–vis absorption of BTNO particles were investigated. Photoluminescence (PL) properties show that a broad blue emission was detected for BTNO nanoparticles, and the characteristic Eu3+ion5D0→7FJ(J=1, 2, 3, 4) transitions were observed for the doped samples. Further investigation illuminates that the Eu3+ions substituted for Bi3+ions at A site in the pseudo-perovskite layers. It can be confirmed from high bright fluorescence image and short decay time that the novel orange-red phosphor has the potential applications in luminescence devices.
