| 摘 要： | 用高温熔融法制备了成分为：B2O3-Bi2O3-SrO的新型掺铒硼铋锶酸盐玻璃．测试了样品的发射光谱和吸收光谱．利用Judd—Ofelt理论计算了该玻璃样品的J-O参数（Ω2，Ω4，Ω6）和Er^3＋各相关能级的理论振子强度、实验振子强度等发光参数，并对其发光特性进行了研究．计算结果表明：该硼铋锶酸盐玻璃的共价性强于已被报道的大多数玻璃，且其跃迁几率最大的两个能级为^4I13/2和^4I15／2能级．

| Abstract: | In this paper,novel Er^3＋ - doped B2O3 - Bi2O3 - SrO glasses were prepared by the technique of high-- temperature melting. The J - O parameters （Ω2,Ω4,Ω6）, radiative transition probabilities, absorption and emission spectrometry, calculated and experimental oscillator strengths were calculated by using the theory of Judd--Ofelt. In addition,the luminescence property has been investigated. The results indicate that the covalency of this glass host is larger than many kinds of glasses which have been reported. And the best of its radiative transition probabilities is at the energy level of ^4I13/2 and ^4I15/2 |
