Abstract
Nb5+-doped SrTiO3 (STO) particles were synthesized by a simple hydrothermal reaction at 150 °C for 4h. It was found that the main diffraction peaks of Nb5+-doped STO samples with different dosage of dopants shifted gradually to low angles, indicating the little lattice parameter expansions which result from the partial substitution of Ti4+ (0.061 nm) by Nb5+ (0.064 nm) in perovskite structure. From the lattice parameters, the max Nb5+ dopant concentration is about 2 mol%, and the particles obtained were 200 nm-sized and monodispersed.
