The flash-evaporation method was used to deposit several thin films (1, 1.2, and 1.35 µm thick) of undoped lead iodide on glass slides held at $$150$$ 150 °C and $$200$$ 200 °C. Their X-ray diffraction patterns, scanning electron microscope micrographs, and energy-dispersive spectroscopy spectra revealed crystalline hexagonal 2H-polytypic structure and high stoichiometry ($${\text{PbI}}_{x} ;x \cong...
Zinc oxide and boron-doped zinc oxide (B-ZnO) thin films have been dip coated on glass substrates using sol–gel technique. The ZnO solution was prepared using zinc acetate dihydrate (ZAD) as the starting material. Ethanol and citric acid are used in the sol–gel process as solvent and solution stabilizer, respectively. Doping of boron is achieved by adding a proper molar ratio of boric acid (H3BO3)...
