Investigation of optical, structural and morphological properties of nanostructured boron doped TiO2 thin films

Abstract

Pure and different ratios (1, 3, 5, 7 and 10%) of boron doped TiO2 thin films were grown on the glass substrate by using sol-gel dip coating method having some benefits such as basic and easy applicability compared to other thin film production methods. To investigate the effect of boron doped on the physical properties of TiO2, structural, morphological and optical properties of growth thin films were examined. 1%boron-doping has no effect on optical properties of TiO2 thin film; however, optical properties vary with > 1%. From X-ray diffraction spectra, it is seen that TiO 2 thin films together with doping of boron were formed along with TiB2 hexagonal structure having (111) orientation, B 2O3 cubic structure having (310) orientation, TiB 0.024O2 tetragonal structure having rutile phase (110) orientation and polycrystalline structures. From SEM images, it is seen that particles together with doping of boron have homogeneously distributed and held onto surface. © Indian Academy of Sciences.
