Abstract
We report here the synthesis and characterization of a host of ZnS-based ph osphor materials employing microwave radiation. Activator ions such as Cu, Bg and Mn have been successfully doped. Microwave method enables higher dop ing percentage of Cu, upto 10% in ZnS. These materials have been characteri zed using XRD, SEM, EPMA, and the emission spectral studies. The effect of higher doping concentrations and narrow particle size distribution of the m icrowave-prepared samples is clearly reflected in the emission spectra, (C) 2001 Elsevier Science Ltd.
