In order to improve the absorption cross section and increase the photoluminescence efficiency of Tb
3+
ions doped silica thin film
SnO
2
nanocrystals with larger absorption cross sections were introduced into the silica thin films
and the greatly enhanced photoluminescence intensity was obtained because of resonant energy transfer mechanism. Firstly
Tb
3+
and SnO
2
nanocrystals codoped silica thin films were fabricated by use of sol-gel and spin coating methods according to the restrictive crystallization principle. The characteristic photoluminescence emission intensity of Tb
3+
ions at 541 nm was enhanced by two orders of magnitude for the film sensitized by SnO
2
nanocrystals with the optimized Sn
4+
concentration. The photoluminescence excitation spectra indicate the non-radiative energy transfer process that takes place between Tb
3+
ions and surface of SnO
2
nanocrystals. Meanwhile
the photoluminescence intensity decay curves suggest the partial incorporation of Tb
3+
ions into the SnO
2
sites
which explains the greatly improving energy transfer efficiency. All these results indicate that SnO
2
nanocrystals could be benefit for enhanced photoluminescence of Tb
3+
ions doped silica thin film as a potential sensitizer.
