CdS semiconductor nanoparticles are used to improve the luminescence properties of europium(III) -doped matrices such as silica xerogel and silica nanoparticles, both prepared by a sol-gel method as well as zeolite NaY. The impregnation of CdS nanosized clusters on an Eu3+-doped matrix enhances the luminescence of both dopants. Additionally, the luminescence of the materials can be improved by thermal treatment and by changing the Eu3+/CdS molar ratio. Eu3+ emission spectra show changes in the intensities of the bands at 595 and 612 nm, depending on the structural order of the oxide matrices.
