采用低成本、简便的溶液法合成了纤锌矿型铜铟硫(CuInS 2)纳米片。通过使用单乙醇胺(MEA)的溶剂,在氮气氛下在140 °C下进行反应1小时。实验结果表明,产物具有良好的结晶性、单晶型和化学计量组成。溶剂材料、反应时间和温度对纤锌矿CuInS 2纳米片的形成有重要影响。并对可能的生长机理进行了讨论。纤锌矿-CuInS 2的宽化学计量比意味着该工作可能为合成I-III-VI 2三元半导体纳米晶作为新型太阳能材料提供新的战略途径。
Wurtzite copper indium disulfide (CuInS2) nanoplates were synthesized via a low-cost, facile solution-based method. The reaction was carried out at 140 °C for an hour under nitrogen atmosphere by using the solvent of monoethanolamine (MEA). The experimental results revealed that the products had good crystallinity, monomorphology and stoichiometric composition. The solvent material, reaction time and temperature played important roles in the formation of the wurtzite CuInS2nanoplates. The possible growth mechanism was also proposed and discussed. And the wide stoichiometry of the wurtzite-CuInS2implies that this work may offer a new strategic approach for the synthesis of I–III–VI2ternary semiconductor nanocrystals as new solar energy materials.
