Random Lasing Action from Randomly Assembled ZnS Nanosheets

Random Lasing Action from Randomly Assembled ZnS Nanosheets

<p>Abstract</p> <p>Lasing characteristics of randomly assembled ZnS nanosheets are studied at room temperature. Under 266-nm optical excitation, sharp lasing peaks emitted at around 332 nm with a linewidth less than 0.4 nm are observed in all directions. In addition, the dependence...
