Amorphous AsS, AsSe and AsSe bulk glasses and thin films were prepared by the melt quenching technique and vacuum thermal evaporation, respectively, on different substrates. The density () - determined by the simple and cheap method of precise weighting, refractive index (), structural arrangement - inferred from Raman spectroscopy, and nanohardness ( ) were determined for all the studied materials in both bulk and thin film states. It is found that regardless of the chemical composition, the bulk glass density, refractive index and nanohardness are higher in comparison with those of the corresponding virgin and by annealing relaxed thin films, and the observed differences are discussed. The almost negligible influence of the substrate on the thin films density, structural arrangement and nanohardness, was observed.
分别采用熔体淬火技术和真空热蒸发法，在不同衬底上制备了非晶态AsS、AsSe和AsSe块状玻璃及薄膜。通过简单且成本低廉的精确称重法测定了密度（），利用拉曼光谱推断了折射率（）和结构排列，并测定了所有研究材料在块状和薄膜状态下的纳米硬度（）。结果发现，无论化学成分如何，块状玻璃的密度、折射率和纳米硬度均高于相应的原始薄膜以及经退火松弛后的薄膜，且对观察到的差异进行了讨论。观察到衬底对薄膜密度、结构排列和纳米硬度的影响几乎可以忽略不计。
