Elemental composition and luminescent characteristics of Zns:Cu powders, obtained by self-propagating high-temperature synthesis using Nacl as a flux

摘要

This work was devoted to ultrafine ZnS:Cu powders obtained by self-propagating high-temperature synthesis (SHS) using NaCl as a flux. Powder particles size and morphology were characterized by scanning electron microscopy (SEM). Elemental composition was measured by local energy-dispersive X-ray spectroscopy (EDS). Photoluminescence (PL) and luminescence excitation (PLE) spectra were studied. The influence of different amount of NaCl as a flux in synthesis of ZnS:Cu on its elemental composition and luminescent characteristics was investigated.
