dc.description.abstractSnO2 nanoparticles dispersed in Eu3+ doped silica (SnO2-SiO2:Eu3+) were prepared at a low temperature (185 °C) in ethylene glycol medium. Transmission electron microscopy studies on as-prepared samples have established that SnO2nanoparticles having size of 4.6 nm are uniformly covered by the SiO2matrix. Significant extent of exciton mediated energy transfer between SnO2and Eu3+ions in heat treated SnO2-SiO2:Eu3+samples has been attributed to the diffusion of Eu3+ions from the SiO2matrix to the near vicinity of SnO2nanoparticles and its incorporation in the SnO2 matrix. On the other hand, very weak energy transfer exists for SnO2: Eu3+ nanoparticles heated at different temperatures due to the phase segregation of Eu3+ions from the matrix.
