| Abstract: | Nanostructured ZnO thin film on a glass slide has been prepared by the spin-coating method together with calcining at 500 °C for 2 h in flowing oxygen atmosphere. The grain size of the ZnO nanoparticles is estimated to be ca. 12 nm as determined by the absorption spectrum and powder X-ray diffraction analysis. The photoluminescent peaks that centered at ca. 379 and 388 nm are assigned to the spontaneous emission and exciton–exciton emission, respectively. The thin film also shows frequency-tripled properties for the output when the laser beam of 1.06 μm is input in convergent beam. |
