Abstract
Micro- and nanocrystalline ZnO powders and films have been prepared under mild hydrothermal conditions, and their spectroscopic and lasing properties have been investigated. The polycrystalline ZnO films showed stimulated emission with a lasing threshold of 0.67 MW/cm2. Analysis of their lasing behavior suggests that the stimulated emission is generated by individual crystallites, each acting as a microlaser.
