摘要:
用高温固相法制备了Li6SrLa2Nb2O12: Pr3+,并通过X射线衍射仪及荧光光谱仪分析了其结构和发光性质.结果表明: 激发光谱出现NbO7-6吸收和Pr3+的4f → 4f 5d激发跃迁; 发射光谱出现强的绿光发射,其峰值位于491 nm,同时在610 nm处有弱的红光发射,这两种发射分别属于Pr3+的
Abstract:
Li6SrLa2Nb2O12: Pr3+was prepared by the high-temperature solid-state method, which the inorganic crystal structure and the photoluminescence properties were investigated by means of X ray diffractometer and fluorescence spectrophotometer. The results showed that the excitation spectrum consisted of two bands corresponded to the charger transfer transition of NbO7-6 complex and the 4f → 4f 5d transition of Pr3+. The emission spectrum showed a strong green emission peak at 491 nm and a weak red emission peak at 610 nm, the two emission peaks originated from the 3P0→ 3H4 and 1D2→ 3H4 transitions of Pr3+, respectively. The optimal doping concentration of Pr3+ in Li6SrLa2Nb2O12 is 0.5 mol%.
