One-dimensional Mn(2+)-doped CdS nanocrystals were synthesized by the hydrothermal route. The products were characterized by SEM, EDS, XRD, TEM, HRTEM and PL, respectively. The results revealed that dopant Mn2+ completely substitutes Cd2+ in CdS nanocrystals, and the product was of good crystallite. Further more, a complete suppression of the emission from surface states at room temperature when doping with ions Mn2+ has been observed.
通过水热法合成了一维掺锰（Ⅱ）的硫化镉纳米晶体。分别用扫描电子显微镜（SEM）、能谱仪（EDS）、X射线衍射仪（XRD）、透射电子显微镜（TEM）、高分辨透射电子显微镜（HRTEM）和光致发光（PL）对产物进行了表征。结果表明，掺杂剂锰（Ⅱ）在硫化镉纳米晶体中完全替代了镉（Ⅱ），产物具有良好的微晶结构。此外，观察到在室温下掺杂锰（Ⅱ）离子时表面态发射被完全抑制。
