Paper Abstract

We succeeded in synthesizing phosphorus (P)-doped ZnO microspheres using a ZnO sintered target containing 2 wt% of P2O5 by pulsed laser ablation in air. Phosphorus is one of the prospective materials for p-type ZnO. Raman peak of the Pdoped ZnO microspheres indicated local vibrational mode of P-O. Additionally, room-temperature photoluminescence (RT-PL) properties of the microsphere were investigated under laser excitation using a Q-switched Nd:YAG laser (355 nm) and He-Cd laser (325 nm) in the air. P-doped ZnO microspheres showed whispering-gallery-mode (WGM) lasing in ultraviolet (UV) region by optical pumping.
