| 摘 要： | 用水热方法合成了一维Mn2 掺杂CdS纳米晶体.产品分别用SEM,EDS,XRD,TEM,HRTEM和PL等技术进行了表征.结果表明,掺杂Mn2 完全替代了CdS晶格中Cd2 的位置,产品具有较好的结晶性.荧光光谱中,CdS纳米晶体表面缺陷态的发射峰被完全抑制,只能观察到单一的Mn2 的发射峰.

| Abstract: | One-dimensional Mn2 -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. |
