使用乙二醇作为溶剂，通过连续流介观流体反应器合成了铜锌锡硫化物（CZTS）纳米颗粒。在本研究中，反应温度、停留时间和前体浓度用于控制 CZTS 组成。研究发现，CZTS 最初是通过 Cu2−xS 的成核形成的，随后根据阳离子反应性掺入剩余的金属物质，其中 Cu+>Sn+4>Zn+2。 CZTS 纳米颗粒薄膜在含硒气氛中退火，形成粒径大得多的铜锌锡硒化物纳米颗粒。
Copper zinc tin sulfide (CZTS) nanoparticles were synthesized using ethylene glycol as a solvent via a continuous flow mesofluidic reactor. In this study reaction temperature, residence time, and precursor concentrations were used to control CZTS composition. It was found that CZTS initially forms by the nucleation of Cu2−xS with subsequent incorporation of the remaining metal species as dictated by the cation reactivity, where Cu+>Sn+4>Zn+2. CZTS nanoparticle films annealed in a selenium-containing atmosphere resulted in the formation of copper zinc tin selenide nanoparticles with much larger particle sizes.
