CdS_1−xSe_x nanomaterial with high optical and structural quality has been synthesized in ammonium water via a simple hydrothermal reaction. Structural and compositional analyses suggest that the CdS_1−xSe_x synthesized in ammonium water (NH₃·H₂O) medium has better crystallinity and more Se content compared with that of CdS_1−xSe_x synthesized in sodium hydroxide (NaOH) solution medium. Photoluminescence spectra show that the CdS_1−xSe_x synthesized in NH₃·H₂O solution exhibits stronger red luminescence than that of the CdS_1−xSe_x synthesized in NaOH solution. Transmission electron microscopy confirms that the size of the CdS_1−xSe_x synthesized in NH₃·H₂O solution is obviously larger than that of the CdS_1−xSe_x synthesized in NaOH solution. Basing on these results, the mechanism of CdS_1−xSe_x formed in NH₃·H₂O was compared with that of the CdS_1−xSe_x synthesized in NaOH solution media.

通过简单的水热反应在铵水中合成了具有高光学和结构质量的CdS _1-x Se _x纳米材料。结构和组成分析表明，与在氢氧化钠（NaOH）中合成的CdS _1-x Se _x相比，在铵水（NH ₃ ·H ₂ O）介质中合成的CdS _1-x Se _x具有更好的结晶度和更多的Se含量。溶液介质。光致发光光谱表明，在NH ₃ ·H ₂ O溶液中合成的CdS _1-x Se _x呈现出比CdS更强的红色发光。_1-x Se _x在NaOH溶液中合成。透射电子显微镜证实，在NH ₃ ·H ₂ O溶液中合成的CdS _1-x Se _x的尺寸明显大于在NaOH溶液中合成的CdS _1-x Se _x的尺寸。基础上这些结果，硫化镉的机构_{-X 1}硒_X形成在NH ₃ ·H ₂ O的与CD的相比，_1-X硒_X在NaOH溶液中的媒体合成。
