We give the spectroscopic evidence of energy transfer to erbium ions provided by SnO{sub 2} nanocrystals in silica. The spectral and time resolved analysis of the nanocluster luminescence resonant with Er{sup 3+} transitions demonstrates that erbium ions take part to energy-transfer mechanisms with an efficiency of about 20%. The spectral features of erbium emission excited by energy transfer allow to ascribe it to Er{sup 3+} sites in ordered environments, nearby crystalline tin-dioxide nanoclusters.
