Influence of the ZnO nanoparticle sizes and morphology on the photoinduced light reflectivity
چکیده انگلیسی
We have established a principal possibility of changes of the light reflectivity at the wavelength of 633 nm (He-Ne laser) under influence of the external laser light. The changes are very sensitive to the wavelength of the photoinduced laser. We have chosen two types of the photoinduced lasers: UV nitrogen 7 ns laser at wavelength 371 nm heating near the absorption edge and the 10 ns 1064 nm Nd:YAG laser with wavelength 1064 nm. The power dependences of the reflectivity were studied. Possible explanation of the observed effects is presented following the conception of the nano-trapping levels. These results have been obtained from two ZnO thin films prepared from principally different deposition parameters leading to different particle features and morphologies.
