Description
Summary:ZnO nano and micro structures have attracted tremendous attention due to its remarkable photoluminescence property. In this work we report the photoluminescence characteristics of water suspended ZnO nanoparticle in isolated form and also as composite with silica microspheres. The objective is to develop a new material for optoelectronic application, particularly as an active medium for a tunable laser. We have observed significant increase in the emission intensity of ZnO in the presence of silica. These observations indicate that the composite can act as a random laser
