研究了在水溶性聚合物[聚乙烯醇和明胶]存在下合成的超分散CuI粒子的形态、结构和光学性质。结果表明，所形成的CuI粒子呈圆形，大小在5 ~ 20 nm之间。颗粒形成聚集体，其形状和尺寸由稳定剂的性质决定。它是建立，在明胶的存在下，六方和立方修改的CuI纳米粒子形成，而在聚（乙烯醇）的存在下，粒子只有立方修改。所研究的CuI胶体溶液是稳定的，相对于聚集在很长一段时间内，然而，在其老化过程中，在室温下，CuI纳米粒子的形态和结构特性的变化。
Morphology, structure, and optical properties of ultradisperse CuI particles synthesized in the presence of water-soluble polymers [poly(vinyl alcohol) and gelatin] are studied. It is shown that forming CuI particles are roundish with the sizes varying from 5 to 20 nm. The particles form the aggregates whose shapes and sizes are governed by the nature of stabilizing agent. It is established that, in the presence of gelatin, CuI nanoparticles of hexagonal and cubic modifications are formed, while in the presence of poly(vinyl alcohol), particles only of cubic modification. The studied CuI colloidal solutions are stable with respect to aggregation over long time; however, during their aging at room temperature, morphological and structural properties of CuI nanoparticles are changed.
