【Abstract】 Nano particles of zinc sulfide were synthesized by using zinc sulfate and hydrogen sulfide as source materials. Effects of the initial reactant concentration, reaction temperatures and pH value on the product size and yield were investigated and the optimum conditions were determined. Well dispersed nano particles with a sphalerite crystal phase and an average size of 7?nm were prepared. The crystal structure, size and morphology of the product were also characterized by XRD and TEM.更多还原
