Generation of white light from co-doped (Cu and Mn) ZnSe QDs
Source abstract
Abstract
White light generation is achieved by single-step co-doping of copper and manganese into the robust ZnSe quantum dots (QDs) which were synthesised using a wet chemical route.Photoluminescence (PL) emission spectra revealed three peaks related to blue (ZnSe), green (copper related) and orange (manganese related).The PL spectra indicated no surface and/or trap state related emission.Photoluminescence excitation (PLE) measurements confirmed co-doping of copper and manganese in the same QD.PLE spectra recorded with emission wavelength fixed at copper and manganese showed a band edge at the same position, indicating the incorporation of both copper and manganese in the same QD.Time-resolved PL measurements suggest an atomic like nature of Mn and Cu in ZnSe QDs.
