摘要:

高折射率和非线性光学玻璃可以用于高速光开关、光学存储器、新型光纤和光学运算元件等,其研究受到各国科技工作者的高度重视,本文采用熔融淬冷法制备了组成为(85-x)B2O3-15K2O-xSb2O3(x=70, 75, 80, 85)的4组玻璃,测试了玻璃样品的密度、折射率、热学性能、拉曼光谱和吸收光谱,利用玻璃样品的吸收光谱计算了其直接允许光学带隙、间接允许光学带隙及Urbach能量。结果表明:随着Sb2O3含量的增加,玻璃样品的密度从4.445g/cm3逐渐增加到4.767g/cm3,折射率从1.9438增加到2.0058,玻璃转变温度从291℃降低到260℃,玻璃析晶温度从463℃降低到370℃,直接光学带隙从3.2775eV降低到3.1379eV,间接光学带隙从3.1444eV降低到3.0256eV,Urbach能量从0.137eV逐渐减小到0.107eV。说明Sb2O3-K2O-B2O3系统玻璃可以作为新型的非线性光学玻璃候选材料之一。

Abstract:

Nonlinear optical glasses can be used in high-speed optical switch, optical memory, new optical fibers, optical operational elements and so on, so the research on non-linear optical glass has attracted great attention of scientists and technicians all over the world. In this paper, four groups of glasses (85-x) B2O3-15K2O-xSb2O3 (x=70, 75, 80, 85) were prepared by melt quenching method. The density, refractive index, thermal properties, Raman spectra and absorption spectra of the samples were measured. The direct and indirect allowed band gaps and Urbach energy were calculated by the absorption spectra of the samples. The results showed that with the increase of Sb2O3 content, the density of glass sample increased from 4.445g/cm3 to 4.767g/cm3, the refractive index increased from 1.9438 to 2.0058, the glass transition temperature decreased from 291℃ to 260℃, the crystallization temperature of glass decreases from 463℃ to 370℃, the direct optical band gap decreased from 3.2775eV to 3.1379eV, the indirect optical band gap decreased from 3.1444eV to 3.0256eV and the Urbach energy decreased from 0.137eV to 0.107eV. It was concluded that Sb2O3-K2O-B2O3 system glass can be used as one of the new non-linear optical glass candidates.
