Notes:
In this work, Eu3+-doped CdS nanocrystals embedded in a SiO2 matrix were synthesisedby a sol-gel method since this method confers a great chemical homogeneity, and allows in-situgeneration and controlled growth of CdS nanocrystals within the silica glass. The influence of thesol-gel conditions on the Eu3+ optical response has been investigated. The synthesis conditions canbe varied to modify the structure of the material, and the dispersion of the rare earth ion, within thesilica matrix. From the optical analysis an energy transfer appears from CdS nanoparticles to Eu3+ions but also a back transfer Eu3+ to CdS nanoparticles is evidenced
