研究了Ｃｄ２＋掺杂的ＺｎＳ纳米晶的光致发光特性，结果表明，当Ｃｄ的掺杂量较低时（≤５％，摩尔分数）；ＺｎＳ纳米晶试样的荧光强度显著提高，Ｃｄ的掺杂量为０．５％时，掺杂试佯的相对荧光强度约为未掺杂试样的５倍，发射光谱明显宽化随着Ｃｄ含量的提高，试样的激发光谱（３５０ｎｍ→４８８ｎｍ）和发射光谱（由蓝→绿→红）红移，当Ｃｄ含量≥５％时，其发射光谱与ＣｄＳ纳米晶一致，但荧光强度比Ｃｄｓ纳米晶高．ＸＲＤ分析显示，掺杂试样的晶格结构由Ｃｄ的掺杂量决定．
The photoluminescence (PL) characteristics of CdS-doped ZnS nanocrystals were studied. The results showed that the fluorescence intensity of ZnS nanocrystalline samples increased significantly when the doping amount of Cd was lower than 5% (molar fraction) When the impurity amount is 0.5%, the relative fluorescence intensity of the doped sample is about 5 times that of the undoped sample, and the emission spectrum is obviously broadened. With the increase of Cd content, the excitation spectrum (350nm → 488nm) And emission spectra (from blue → green → red). When the content of Cd is more than 5%, the emission spectrum is consistent with that of CdS nanocrystals, but the fluorescence intensity is higher than that of Cds nanocrystals. XRD analysis shows that the lattice structure of the doped sample is determined by the doping amount of Cd.
