A novel 6SrO center dot 6BaO center dot 7Al(2)O(3) (S6B6A7) thin film deposited onto soda lime float glass via sol-gel dip coating technique is reported. The morphological and compositional properties of the S6B6A7 thin films have been investigated using scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) revealing that the films were composed of S6B6A7 nanoparticles. The optical properties of the S6B6A7 films are affected by sol concentration, film thickness and annealing temperature as revealed by UV-vis transmittance. The transparency of S6B6A7 films improved on increasing annealing temperature up to 450 degrees C in air. The S6B6A7 films prepared using 2, 5, and 8 (wt.%) sols and annealed at 450 degrees C exhibit an average transmittance of over similar to 91% in wide visible range. (C) 2009 Elsevier B.V.
