Bi2O3-B2O3二元系统玻璃的网络结构形成与光学性能研究
Vitreous Network Formation and Optical Characteristics of Glasses Within Bi2O3-B2O3 Binary System
摘要
Abstract
A series of Bi2O3-B2O3 bismuthate glasses were prepared by melt-anneal method. We investigate the oxygen competition mechanism between B2O3 and Bi2O3 with different Bi/B mole ratio, and mainly discuss the dependence of glass composition upon their structural and optical properties. The formation of vitreous network of Bi2O3-B2O3 binary glasses were analyzed by absorption and Raman spectra, and their density, refractive index were measured. The results show that both of Bi3+ and B3+ are glass formers; Raman intensity shows an evident variation centered at 600 cm-1: Raman peaks in low-energy band are associated with bismuth ions introduced to the glass medium, while Raman peaks in high-energy band are associated with the boron-oxygen structures.关键词
