摘 要：Tb3+-doped ZnSe and ZnSe/ZnS nanocrystals were synthesized using modified hot-injection method.The observation of the characteristic quantum dots absorption features in a time-gated excitation spectrum was recorded while monitoring Tb3+ emission at 545 nm provided direct evidence for successful incorporation of dopant ions into semiconductor host.Relatively long decay time（1.5 ms） of Tb3+ emission indicated that dopant ions were well protected from interaction with surface ligands.Emission properties of core ZnSe:Tb3+ nanocrystals were only slightly modified upon growth of ZnS shell..
