| 摘 要： | 以异丙醇为溶剂，醇热法制备Zn0.5Cd0.5S和Ag2S或CuS掺杂的Zn0.5Cd0.5S纳米晶体，考察了这些纳米晶体在可见光区域的光致发光性能。结果表明，反应温度和反应时间、掺杂剂的浓度和种类对Zn0.5Cd0.5S的发光性能有很大的影响，相比未掺杂Zn0.5Cd0.5S纳米晶体而言，Ag2S或CuS掺杂后其光致发光强度明显增强、半高宽更宽。

| Abstract: | Zn0.5Cd0.5S nanocrystals and their derivatives doped with Ag2S or CuS were synthesized via a solvothermal process using isopropanol as the solvent. The optical properties of the as-prepared samples were investigated in the visible light region. The results show that the nature and concentration of dopants as well as preparation conditions (reaction temperature and time) have a great influence on the photoluminescence (PL) spectra of Zn0.5Cd0.5S nanocrystals. The Zn0.5Cd0.5S nanocrystals doped with CuS and Ag2S exhibit a stronger PL intensity and wider FWHM (full width at half maximum) in the visible light region compared with the undoped Zn0.5Cd0.5S. |
