| 摘要: | 通过传统熔融-淬冷技术制备GeSe2-Ga2Se3-RbBr新型硫卤玻璃, 确定其玻璃形成区. 讨论了RbBr对样品物理、热学和光学性能的影响, 其材料色散通过Sellmeier方程计算获得, 样品的直接带隙和间接带隙利用Tauc公式计算得出. 结果表明: 该系统玻璃具有较宽的玻璃形成区, 并且在覆盖可见至远红外的宽广多光谱范围内(0.6~16μm)具有良好的透光性能. 随着卤化物RbBr掺杂量的增加, 样品的密度和折射率减小、转变温度Tg降低、短波截止边和零色散波长发生蓝移、光学带隙逐渐增大等, 尤其是其零色散波长从传统硫系玻璃的10μm直接蓝移至近红外激光可作用的2.135μm. 结果表明这些硫卤玻璃可作为多光谱玻璃材料和非线性光学应用. |
| Abstract: | The glass-forming region of the GeSe2-Ga2Se3-RbBr system is determined firstly in this paper by using the traditional melting-quenching technique. The effects of RbBr on the physical, thermal and optical properties of the samples are investigated. The material dispersion are calculated using the Sellmeier equation. The range of operable direct and indirect band-gaps of the samples is calculated based on the Tauc equation. The results indicate that the glass system has a large glass-forming region, and broad transparent region over the entire 0.6-12.5μm. With the increase in RbBr content, the sample’s density, refractive index and the transition temperature Tg decrease, the short-wavelength cut-off edges and zero-dispersion wavelength exhibit a blueshift, and the optical bandgap increases, and it is particularly so for the zero-dispersion wavelength, blue-shifted from 10μm of traditional sulfur glass to 2.135μm of near infrared laser. These properties indicate that these chalcohalide materials can be applied in multispectral glasses and non-linear optical glasses. |
