我们报道了一种以硫化镉为模型体系的IE-VI硫化物溶胶-凝胶合成方案。通过对氟苯硫酚与硫化镉纳米晶的表面络合，得到了高浓度的溶胶。然后，通过硫醇氧化反应使颗粒逐步解离，实现受控的聚集和凝胶化。凝胶最终可能被加工成固体整体或薄膜，并干燥以获得透明的纳米结构材料。
We report a scheme for the IE-VI chalcogenide sol-gel synthesis, using cadmium sulfide as a model system. Highly concentrated sols are obtained by surface complexation of CdS nanocrystals with 4-fluopophenylthiol. Controlled aggregation and gelation is then achieved by a progressive decomplexation of the particles via a thiol oxidation reaction. The gels may finally be processed as solid monoliths or thin films and dried to obtain transparent nanostructured materials.
