The Ge25Se75, Ge20Se80 and Ge15Se85 thin films were deposited in specular optical quality from n-propylamine - methanol solvent mixture by spin-coating technique. As-prepared solution processed thin films were thermally stabilized to reduce the content of organic solvent residuals and optical properties, surface topography, composition, structure and chemical resistance of prepared Ge-Se thin films were studied in dependence of annealing temperature. Suitable thermal stabilization temperatures were found for each studied chalcogenide glass composition with respect to maintaining of thin films’ low surface roughness and targeted elemental composition. Stabilized thin films exhibited high refractive index, high chemical resistance, low surface roughness and structure close to source bulk glasses. The experiments proved that used n-propylamine - methanol solvent offered suitable way for preparation of high optical quality Ge-Se thin films by solution based deposition route.

使用多组分溶剂方法沉积和表征具有镜面光学质量的溶液处理的富硒 Ge-Se 薄膜

Ge25Se75、Ge20Se80和Ge15Se85薄膜是通过旋涂技术从正丙胺-甲醇溶剂混合物中以镜面光学质量沉积的。对制备的溶液加工薄膜进行热稳定以减少有机溶剂残留物的含量，并研究了制备的 Ge-Se 薄膜的光学性能、表面形貌、成分、结构和耐化学性与退火温度的关系。就保持薄膜的低表面粗糙度和目标元素组成而言，为每种研究的硫属化物玻璃组合物找到了合适的热稳定温度。稳定的薄膜表现出高折射率、高耐化学性、低表面粗糙度和接近源块状玻璃的结构。
