Nanoparticles of CdS, TiO2 and CdS coated with TiO2 (CdS/TiO2) are prepared respectively in reversed microemulsion which is made up of Brij35/n-hexanol/cyclohexane/water. The absorption of CdS/TiO2 composite nanoparticle in the range of visible light is stronger than the sum of CdS and TiO2. Both of the particles of CdS and TiO2 show the obvious fluorescence spectrum, which of TiO2 is much stronger than that of CdS when they are in the same concentration. However, the fluorescence of TiO2 is quenched and that of CdS decreases slightly in the CdS/TiO2 composite nanoparticle.
