摘要:
利用简化的速率方程研究不同激发波长条件下Er3+:PLZT陶瓷的1 550 nm荧光特性。分析荧光强度随激发光强度和Er3+掺杂浓度的变化情况以及 ETU 和ESA 对1 550 nm 荧光发射的影响。结果表明,掺Er3+浓度增加需伴随较大的激发光强度才能得到较强的荧光强度，且上转换对1 550 nm荧光有一定抑制作用。
Abstract:
The 1550nm fluorescence characteristics of Er3+-doped lead lanthanum zirconate titanate (PLZT )ceramics excited at different wavelengths were investigated by simplified rate equation the-ory. The influence of fluorescence excitation intensity and Er3+-doped concentration on the photoluminescence characteristics and the effects of energy transfer upconversion(ETU) and excited state absorption(ESA) on the photoluminescence were analysed. The results show that the 1550nm fluorescence intensity increases with Er3+doped concentration and excitation intensity and the upconversion has a certain inhibitory effect on the fluorescence of 1550 nm.
