Abstract

Abstract: Y doped BaZrO3 hollow nanospheres with different doping contents were hydrothermally synthesized. Y was successfully introduced into the lattice and replaced the Zr at B position of perovskite. The mean particle size varied from 180 nm to 300 nm by elevating the Y content. Pure cubic perovskite phase formed within 3% Y doping content. When excited by 410 nm laser, these hollow nanospheres emitted 503 nm light at room temperature. The PL intensity was positively related to Y doping content due to the increased oxygen vacancies that were induced by Y doping.

Key words: perovskite, hollow nanospheres, doping, photoluminescence
