Abstract
Luminescence properties of hydrothermally and solvo-hydrothermally (water-acetonitrile) grown Mn doped ZnS at a reaction temperature of 200 °C is studied. The photoluminescence (PL) emission intensity of solvo-hydrothermally grown Mn doped ZnS shows high luminescence intensity as compared to that of grown by hydrothermal method. ZnS with Mn 3 wt% doping, grown by S-H method exhibit high luminescence yield at yellow-orange region and 367 nm, is contributed to increase of frozen sulphur vacancy population and specific area of grain boundary. The chromaticity coordinates (CIE) of the observed yellow-orange emission from the samples are calculated, which fall in the yellow-orange region.
