The results showed that cds nanoparticles showed good dispersion in water and ethanol, effectively prevented the aggregation of cds nanoparticles, and the fluorescence characteristics of nanoparticles were enhanced. The average size of CdS nanoparticles was 6~8 nm. Yang Jianyun [18]. cds nanoparticles with small molecular compound as colloidal stabilizer as non-aqueous solvent were prepared, and white cds powder was redispersed in non-solvent.
