二元SnO− SiO2和三元SnO− SnF 2 − SiO2玻璃作为含铅玻璃的潜在替代品,用于开发使用偏振光的光学元件。本文报道了光学和热性质(包括非常小的光弹性常数,PEC)。对于含有43.6mol%SnO的二元玻璃,在波长632.8nm处测得PEC的最小值(-0.008 × 10− 12 Pa −1)。氟含量为8 - 9 mol%的三元玻璃提供了非常小的PEC(-0.039 × 10 - 12 Pa-1)和蓝移的光学吸收边(47.0 mol%的SnO+ SnF 2)。用显微拉曼光谱和~(119)Sn、~(29)Si、~(19)F核磁共振谱研究了硅酸盐玻璃的局域结构。结果表明,零PEC玻璃具有离散的硅酸盐结构,具有Meta硅酸盐和焦硅酸盐单元。讨论了零光弹性质与硅酸盐结构的关系。
Binary SnO−SiO2and ternary SnO−SnF2−SiO2glasses are investigated as potential alternative to lead containing glasses for the development of optical components using polarization light. Optical and thermal properties (including very small photoelastic constant, PEC) are reported herein. A minimum value of PEC (–0.008 × 10−12Pa−1) is measured at a wavelength of 632.8 nm for the binary glass containing 43.6 mol% of SnO. The ternary glasses with fluorine of 8 − 9 mol% provide a very small PEC (–0.039 × 10−12Pa−1) and blue-shifted optical absorption edge for 47.0 mol% of SnO+SnF2. The local structure of the silicate glass is investigated by micro-Raman and119Sn,29Si, and19F nuclear magnetic resonance spectroscopies. It turns out that the zero PEC glass possesses a discrete silicate structure with meta- and pyro-silicate units. The relationship between the zero photoelastic property and the silicate structure is discussed.
