Synthesis of Wurtzite-Type ZnMgS by the Pulsed Plasma in Liquid

Wurtzite-type ZnMgS (w-ZnMgS) nanoparticles were synthesized using the pulsed plasma in liquid method. By the pulsed plasma generated between two electrodes made of ZnMg alloy in liquid sulfur, we produced w-ZnMgS nanocrystals mixed with Zn2Mg and MgS. Higher purity w-ZnMgS sample was achieved by annealing at 773 K. The synthesized ZnMgS nanoparticles were of spherical shape and contained of many crystal defects (stacking faults). Ultraviolet–visible (UV–vis) absorption spectroscopy analysis of the synthesized w-ZnMgS showed absorption edge broadening and appearance of a small absorption band at around 400 nm even without doping.
