Hydrothermal Synthesis and Characterization of Nb⁵⁺-Doped SrTiO₃ Powders

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.
