以1-辛醇和环己烷的混合物为反应介质，以油胺为表面活性剂，在“软化学”体系中成功合成了单分散aggas2三维纳米花。采用x射线衍射仪（XRD）、透射电镜（TEM）和高分辨率透射电镜（HTEM）对制备产物的晶相、形貌和化学成分进行了表征。结果表明，合成的aggas2纳米花呈四边形结构，具有三维花状结构。对照实验表明，通过调节反应参数，如辛醇与环己烷的比例、脂肪醇碳链长度、油胺浓度等，aggas2纳米晶体的形状可以很容易地从三维纳米花（50 nm）转变为纳米颗粒（10-20 nm）。研究了制备的aggas2纳米花和胶体的紫外可见光谱和PL光谱。此外，通过表面光电压谱进一步研究了aggas2纳米花的光电子能量转换（SPV）。
Monodispersed AgGaS2three-dimensional (3D) nanoflowers have been successfully synthesized in a “soft-chemical” system with the mixture of 1-octyl alcohol and cyclohexane as reaction medium and oleylamine as surfactant. The crystal phase, morphology and chemical composition of the as-prepared products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and high-resolution TEM (HTEM), respectively. Results reveal that the as-synthesized AgGaS2nanoflowers are in tetragonal structure with 3D flower-like shape. Controlled experiments demonstrated that the shape transformation of AgGaS2nanocrystals from 3D nanoflowers (50 nm) to nanoparticles (10–20 nm) could be readily realized by tuning the reaction parameters, e.g., the ratio of octanol to cyclohexane, the length of carbon chain of fatty alcohol, the concentration of oleylamine, etc. The UV–vis and PL spectra of the obtained AgGaS2nanoflowers and colloids were researched. In addition, the photoelectron energy conversion (SPV) of AgGaS2nanoflowers was further researched by the surface photovoltage spectra.
