Abstract

Luminescence of nanocrystalline ZnSe:Mn2+ and ZnSe:Cu2+ prepared via an organic chemical synthesis method are described. The spectra show distinct ZnSe, Mn2+ and Cu2+ related emissions, all of which are excited via the host lattice. The Mn2+ emission wavelength depends on the concentration of Mn2+incorporated into the ZnSe lattice, which is attributed to the presence of Mn2+ pair-states at higher concentrations. The ZnSe:Cu2+ luminescence was studied as a function of the crystal-size. Temperature-dependent photoluminescence spectra and photoluminescence lifetime measurements are also presented and the results are compared to those of Mn2+ and Cu2+ in bulk ZnSe.
