摘要

在残压为 1.10-3 Pa 的石英安瓿瓶中，通过熔体淬火技术合成了 As2Se3-GeSe2-ZnTe 体系的新型钙钛矿样品。所研究体系的试样是在符合初始化合物物理化学特征的条件下通过直接单温合成制备的。块状样品的状态（玻璃状、结晶状、玻璃状+结晶状）通过目视、X 射线衍射和显微分析得到证实。根据所进行的合成和分析结果，我们勾勒出了该体系中的玻璃化区域。它位于 As2Se 3-GeSe2 侧，部分位于 As2Se3-ZnTe （0 至 5 摩尔 % ZnTe）和 GeSe2 -ZnTe （0 至 15 摩尔 % ZnTe）侧。ZnTe 在玻璃中的最大溶解度为 20 摩尔%。在 XRD 勘测的样品中发现了结晶相 As2ZnGe。

GLASS-FORMATION IN THE As2Se3-GeSe2-ZnTe SYSTEM

New chalcogenide samples from the As2Se3-GeSe2-ZnTe system are synthesized by melt quenching technique in evacuated to a residual pressure of 1.10-3 Pa quartz ampoules. The specimens from the investigated system are prepared by direct mono-temperature synthesis with conditions conformed to the physico-chemical features of the initial compounds. The state of the bulk samples (glassy, crystalline, glassy + crystalline) is proven by visual, X-ray diffraction, and microscopic analyses. The glass-forming region within the system is outlined using the results of the performed syntheses and analyses. It lies on the As2Se 3-GeSe2 side and partially on the As2Se3-ZnTe (from 0 to 5 mol % ZnTe) and GeSe2 -ZnTe (from 0 to 15 mol % ZnTe) sides. The maximum solubility of ZnTe in the glasses is 20 mol %. A presence of a crystallizing phase As2ZnGe is registered in the XRD-investigated samples.
