摘要：

The vapor diffusion sol-gel (VDSG) method was employed for the room-temperature synthesis of similar to 10 nm, aliovalently doped 0.4, 0.8, and 1.6 mol% La:BaTiO3 and 0.4, 0.6, and 1.2 mol% Dy:BaTiO3 nanocrystals. Maximum ensemble relative permittivities of 176 and 208 were observed in the 0.8 mol% La: BaTiO3 and the 1.2 mol% Dy: BaTiO3 nanocrystals, respectively, relative to 89 for undoped BaTiO3 (at 1 MHz, 25 degrees C) due to local disorder induced by aliovalent substitution.
