Optical and microstructure analysis of ZnO particles via sonication effect

Over the last few years, Zinc Oxide (ZnO), a well-known II-VI semiconductor has gain intensive research due to its direct wide band gap (3.37 eV), possess high exciton binding energy (60 meV at 300K), exhibit piezoelectricity and as well as a biocompatibility. These attractive properties suggest a practical application particularly in UV sensing and UV emission device. Realizing to this, a numerous studies have been conducted notably on synthesizing ZnO particle and examine its optical behavior.
