| Abstract: | Y doped BaZrO3 hollow microspheres with different doping amounts were hydrothermally synthesized and characterized by TEM,XRD and SEM.The results show that 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 when the doping amount of Y within 3%(molar fraction).When excited by 410 nm laser,these hollow microspheres emitted 503 nm light at room temperatu... |
