| Abstract: | CdS nanoparticles were directly synthesized in aqueous solution at room temperature. Absorp- tion and fluorescence spectra of CdS nanoparticles at different pH values and reaction time were investi- gated. At the same time, the spectroscopic characteristics and application values of the CdS-phenosafranine system were also discussed. |

| Keywords: | CdS nanoparticle absorption spectra fluorescence spectra quantum size effect phenosa- franine |
