摘要： 利用水热法合成了不同掺Y量的BaZrO3中空纳米球，并通过TEM，XRD，SEM等手段对样品进行了表征。结果表明，样品均为中空纳米球，Y掺杂进入BaZrO3晶格，产物均为立方钙钛矿型结构，中空纳米球粒径随Y掺杂量的增加，由180nm增大到300nm。Y掺杂量小于3%时，可得纯相。不同掺杂量的中空纳米球在410nm的光激发下发出503nm的蓝光，并且在掺杂质为0-3%范围内随着Y掺杂量的增加，发光强度逐渐增强。

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
