Photoluminescence and energy transfer study of Eu3+ codoped with CdS nanoparticles in silica glass.

The CdS nanoparticles along with Eu(3+) ions were embedded in silica xerogel by sol gel technique. The samples were studied by TGA, DTA and fluorescence techniques. The result suggested that doping of CdS nanoparticles enhanced the luminescence properties of Eu(3+) even in the gel stage itself and this avoids the need of heating gel at higher temperature. The effects of CdS nanoparticles on the Eu(3+) luminescence were discussed.
