N2 - We succeeded in synthesizing spherical ZnO microcrystals by a simple laser ablation in air, and we obtained ultraviolet whispering-gallery-mode (WGM) lasing from the microcrystal under pulsed laser excitation. In addition, room-temperature electroluminescence from the ZnO microsphere/p-GaN heterojunction was achieved under forward bias. Recently, doped ZnO spherical crystals are successfully synthesized using dopant contained targets and its optical characteristics were investigated.
