| 摘 要： | 在室温和低温(80K)下,对磷酸盐玻璃中 Cr~(3+)离子的吸收光谱、激发光谱、荧光光谱及荧光寿命进行了测量。根据配位场理论对实验结果进行了分析。不同波长激发下,观测到荧光峰值的移动和线宽的变化,对玻璃中 Cr~(3+)离子的浓度猝灭效应进行了讨论。

| Abstract: | The absorption,excitation,fluorescence spectra and lifetime measurements ofCr~(3+) in Ba-phosphate glasses were performed at room temperature and 80K.Theanalysis of the experimental data based on the ligand field theory was carried out.Under various wavelength excitations,the fluorescence peak shifts and variations ofbandwidth were observed.The effect of concentration quenching of Cr~(3+) in the glas-ses was discussed. |
