本論文利用溶劑熱法合成Cu2Zn1-xFexSnSe4粉末。透過更改不同的合成條件，例如:溶熱法反應時間、反應溫度、不同溶劑等。並透過一系列分析來觀察粉末的特性並從中取得最佳化的製備參數。反應物中的金屬陽離子分別來自氯化亞銅、醋酸鋅、醋酸亞鐵、四氯化錫，陰離子硒則來自硒粉。溶劑熱法方面的反應時間是24小時到96小時，反應溫度分別為160°C與180°C。溶劑方面則是將氯化亞銅、醋酸鋅、醋酸亞鐵、四氯化錫溶於乙二胺，硒粉溶於聯胺，並觀察有無聯胺添加對整體四元相產物合成的影響。根據以上實驗的最佳參數以不同醋酸鋅及醋酸亞鐵的比例摻雜並分析其光學特性。

By changing different synthesis conditions, such as: solvothermal reaction time, reaction temperature, different solvents, etc. And through a series of analysis to observe the characteristics of the powder and obtain the optimized preparation parameters. The metal cations in the reactants come from cuprous chloride, zinc acetate, ferrous acetate, and tin tetrachloride, respectively, and the anion selenium comes from selenium powder. The reaction time in the solvothermal method is 24 hours to 96 hours, and the reaction temperatures are 160°C and 180°C, respectively. In terms of solvent, cuprous chloride, zinc acetate, ferrous acetate, and tin tetrachloride were dissolved in ethylenediamine, and selenium powder was dissolved in hydrazine. According to the best parameters of the above experiments, the ratios of zinc acetate and ferrous acetate were doped and their optical properties were analyzed.
