Abstract

Cu_{2 – x}Zn_{1 + 0.5х}SnS₄ copper-deficient solid solutions with the kesterite structure have been synthesized and their unit-cell parameters have been determined for the first time as functions of composition in the range 0 < x ≤ 0.45. The 78-K cathodoluminescence spectra of the Cu_{2 – x}Zn_{1 + 0.5х}SnS₄ (0 < x ≤ 0.30) solid solutions show a band centered at 1.315 eV, which is most likely due to Zn²⁺V_Cu associates—predominant defects. The luminescence of the Cu_{2 – x}ZnSnS₄ solid solutions is due to Сu²⁺V_Cu predominant defects.

摘要

的Cu _{2 - X}的Zn _{1周+ 0.5 х}的SnS ₄铜缺陷与锌黄锡矿结构的固溶体已被合成，并在范围0 <其晶胞参数被确定为在第一时间为组合物的功能X ≤0.45。的Cu的78-K的阴极发光光谱_{2 - X}的Zn _{1周+ 0.5 х}的SnS ₄（0 < X ≤0.30）固溶体显示出带中心在1.315电子伏，这很可能是由于对于Zn ²⁺ V_铜联营为主缺陷。Cu _{2 – x} ZnSnS ₄的发光固溶是由于Сu2 ⁺ V _Cu的主要缺陷。
