不同基质晶体中Nd^(3+)离子的发光特性

Luminescence Character of Nd^(3+) in Different Crystals

本文测量了不同基质晶体中 Nd^(3+)离子的荧光光谱和荧光寿命,计算了荧光分支比。对荧光峰值波长的移动、荧光寿命的变化、分支比的大小及 Cr^(3+)对 Nd^(3+)离子的敏化发光作用进行了讨论。

Fluorescence spectra and lifetime of Nd^(3+) in different crystals were measuredand fluorescence branching ratios were calculated.The transposition of fluorescencepeak wavelength,change of fluorescence lifetime,and branching ratio as well assensitization of Cr^(3+) to Nd^(3+) ions were discussed.
