Abstract

The 12BaO·7Al2O3 (B12A7) thin films have been prepared via sol–gel process. Optical and electrical properties of B12A7 films have been investigated. The films were coated on soda lime float glass by the dip coating process, and annealed in air and hydrogen (H2) at 450 °C for 2 h. The UV absorption edge was red shifted for films annealed in H2 atmosphere. The B12A7 films had high transparency about 90% in wide visible range with maximum of 95% at 575 nm wavelength. The sheet resistance of the 300 nm films corresponding to 90.57 and 0.974 kΩ per square has been observed for air and H2 annealed, respectively.
