摘要

合成了非晶钙源化合物半导体As0.63S2.70Sb1.37Te0.30，并在此基础上制备了薄膜。XRD和光学图像研究表明样品具有非晶态和均匀性。As0.63S2.70Sb1.37Te0.30薄膜在UV-Vis范围内的光学透射光谱在0.7-3.5µm的光谱范围内显示出良好的透明度，在2.05eV处具有单一吸收阈值，在红外中具有2.3的折射率。用光照射薄膜导致透射光谱向IR范围的平行移动。As0.63S2.70Sb1.37Te0.30成分的材料具有高光学透明度和高光学透明度，有望应用于全息存储设备、光学振幅和相位记录器、光学处理单元等。

Synthesis and optical properties of the glassy compound As0.63S2.70Sb1.37Te0.30

The amorphous calcogenide semiconductor As0.63S2.70Sb1.37Te0.30 was synthesized and thin films based on it were obtained. XRD and optical images investigations showed the amorphous and homogeneous nature of the samples. The optical transmission spectrum in the UV-Vis range of As0.63S2.70Sb1.37Te0.30 thin films shows good transparency in the spectral range 0.7-3.5 µm with a single absorption threshold at 2.05 eV and with refractive index in infrared 2.3. The irradiation of films with light leads to a parallel shift of the transmission spectrum to the IR range. The materials with As0.63S2.70Sb1.37Te0.30 composition have high optical transparency have high optical transparency that make they promises for applications in holographic memory devices, optical amplitude and phase recorder, optical processing units and others.

期刊介绍： Chalcogenide Letters (CHL) has the aim to publish rapidly papers in chalcogenide field of research and appears with twelve issues per year. The journal is open to letters, short communications and breakings news inserted as Short Notes, in the field of chalcogenide materials either amorphous or crystalline. Short papers in structure, properties and applications, as well as those covering special properties in nano-structured chalcogenides are admitted.
