摘要
本文详细分析研究了掺钕ＢＧＯ单晶的光谱特性．测量了Ｎｄ（３＋）离子在ＢＧＯ单晶中的吸收谱、荧光谱（４Ｆ３／２→４Ｉ（９／２、１１／２、１３／２）及荧光寿命，并研究了荧光谱的温度效应．计算了跃迁几率、发射截面、分支比和Ω（２、４、６）等光谱参数，和ＹＡＧ：Ｎｄ（３＋）作了比较．
In this paper the data of spectral properties of cubic BGO: Nd3+were reported and a detailed analysis of absorption, luminescence spectra for Nd3+in 4F3/2-4I9/2.11/2.13/2.15/2 transition were carried out. The luminescence lifetime (rlum,of the metastable ,lustate,luminescence line width(aA),spontaneous transition probabilities and stimulated emission transition cross-sections were determined and the dependence of fluorescence on ature is studied
