Abstract

The random laser action with coherent feedback in ZnO nanorod arrays embedded in ZnO epilayers was discussed. By depositing a MgO buffer layer followed by a layer of ZnO thin films onto a vertically well-aligned ZnO nanorod arrays grown on sapphire substrate, the sample was fabricated. Sharp lasing peaks were emitted at around 390 nm with a linewidth less than 0.4 nm in all directions, under 355 nm optical excitation at room temperature. The results show that the random laser action can also be supported in ZnO nanorod arrays.
