Synthesis and luminescence properties of manganese-doped ZnS nanocrystals

摘要

Mn~(2+) doped ZnS nanocrystals were synthesized via aqueous solution precipitation method. The crystal structure of these nanocrystals is found to be cubic. The particle size of as prepared ZnS and (ZnS) Mn~(2+) was found in between the range of 4-6 nm. The optical and photoluminescence studies of Zn_(1-x)Mn_xS (x = 0-5%) have also been performed at room temperature. The absorption and emission intensities were found to be increased on increasing Mn~(2+) concentration (0-5 atom%). The Mn doped ZnS nanocrystals result blue shifted.
