Investigation of Optical Properties on BaSnO 3 Materials

Abstract

Perovskite BaSnO 3 materials were synthesized under hydrothermal condition followed heat treatment at variable temperature 423 - 673 K. Phase structure and morphology and optical properties were characterized. Result showed band gap about 3.31 eV and highly optical transparency in the visible spectral region and average particles size 40 -45 nm. Thermal annealing process has affected on phase structure and luminescence in BaSnO 3 material.
