摘要：
We describe the stimulated emission and the field emission characteristics of ZnO nano-rod crystals synthesized by laser ablation in a background gas. A various type of nanostructured ZnO crystals were successfully synthesized on sapphire substrates, and ZnO crystals were taken out of the substrate by a laser brow-off technique and sonification. ZnO crystals taken out of the substrate showed a lower stimulated emission threshold than those as grown on the substrate under optical excitation, indicating a high quality of the crystalinity.
