摘要
通过液相沉淀法制备出无定形硫化锌粉末,硫化锌粉末经高温热处理后制得纳米硫化锌粉状晶体。具体过程为:将硫化钠溶液缓慢加入酸性的氯化锌溶液中,沉淀、洗涤、干燥后,研磨至200目以上,并在H_2气氛保护下于400℃温度焙烧,制得20~30nm粒径的硫化锌晶体。
ZnS nano - crystals have been prepared by heat - treating the amorphous ZnS powder. The amorphous ZnS were generated by chemical reaction in acid water solution, then dried at 80℃, grinded ≥200 mesh. The ZnS powder were calcined at 400℃in tube electric furnace which was filled with H2. Then the ultrafine ZnS crystals whose size was 20 - 30nm were produced.
