Abstract :
We succeeded in synthesizing Sb-doped ZnO microspheres by ablating a ZnO sintered target containing of Sb with Nd:YAG laser in the air. The structural properties of the microspheres were investigated by Raman scatting studies. The Zn-Sb related local vibrational mode was detected 238 cm-1. Room-temperature photoluminescence properties of the microsphere were investigated under 325 nm He-Cd laser or 355 nm Nd:YAG laser excitation. An ultraviolet (UV) emission and lasing in whispering gallery mode (WGM) were observed from the photoexcited microsphere.
