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 inc...
