| 摘 要： | 本文介绍了用热蒸发技术制备ＣｓＣｕ２Ｉ３薄膜的方法，根据ＣｓＣｕ２Ｉ３的低温吸收谱计算出其激子参数；谱分析表明，ＣｓＣｕ２Ｉ３的电子和激子激发定域在ＣｕＩ４＾２－组成的双链结构之中是导致其光谱复杂性的主要原因。

| Abstract: | This paper introduces a method of manufacturing CsCu2I3 thin films through hot evaporation. According to the absorption spectra at low temperature, the excitonic coefficient of CsCu2I3 was calculated. The spectral analysis shows that the localization of electron and exciton excitations in the twofold Chain created by CuI4(3-) causes the complicated character of the optical spectra of CsCu2I3. |
