摘要：

SnO2:Eu3+ nanoparticles uniformly dispersed in TiO2 matrix were prepared at 185 degrees C in ethylene glycol. Unlike in SnO2:Eu3+, significant improvement in the exciton mediated energy transfer between SnO2 and Eu3+ ions was observed when SnO2:Eu3+ nanoparticles are dispersed in TiO2 matrix, and this is attributed to effective shielding of surface Eu3+ ions present in SnO2:Eu3+ nanoparticles from the vibrations of stabilizing ligand by TiO2 matrix. Annealing the samples at high temperatures leads to formation of Sn1-xTixO2, without significantly affecting the energy transfer process between Eu3+ ions and semiconductor host.
