摘要：Cd1-xMnxS (0 <= x < 1) nanocrystals were synthesized in a hydrothermal process. The nanocrystals were characterized by TEM, XRD, and photoluminescence. The results showed that the MnS crystalline phase appeared in high Mn content in the composite Cd1-xMnxS. The variation of the Cd1-xMnxS emission with Mn content implied different emission mechanisms. The Mn2+ ion emission was probably due to energy transfer via the trap states of CdS nanocrystals in our samples.
