The preparation of barium titanate nanocrystallites doped with RE3+-ions (Eu3+, Nd3+, Yb3+) by sol-gel method has been presented. The effect of sintering temperature on optical properties of obtained nanocrystallites has been investigated. The emission and absorption spectra and luminescence decays measurements were performed. The attention was paid into the size-effects and influence of concentration of active ions on emission properties of RE3+:BaTiO3 nanocrystallites. The effect of BaTiO3 grain sizes on photoluminescence properties of nanocrystallites has been noticed. To explain this differences a detail analysis of luminescence spectra has been performed.
