Lead-free Bi0.5(Na0.4K0.6)0.5TiO3 films have been synthesized by a chemical solution deposition method and deposited on p-Si(111) substrate by spin coating. Powder of the precursor solution heated at 650°C was studied by infrared scattering spectroscopy. The structural characteristics and...

ZnO thin films were prepared on silica glass substrates by a sol–gel spin coating technique. The thickness of the films was about 200 nm. At 370 nm in the ultraviolet region, there is a sharp absorption edge that corresponds to the ZnO intrinsic band gap of 3.30 eV. The structural properties...
