STRUCTURAL AND MORPHOLOGICAL PROPERTIES OF CHEMICALLY SPRAY DEPOSITED TITANIUM DIOXIDE THIN FILMS

Nanostructured titanium dioxide (TiO₂) thin films have been deposited by chemical spray pyrolysis technique onto the glass substrate at 523K.The conditions have been optimized to obtain quality thin films. Films so obtained have been characterized for their structural and morphological properties using X-ray diffraction (XRD) and scanning electron microscopy (SEM) respectively. The structural study revealed that TiO₂ thin films are polycrystalline in nature with tetragonal lattice having preferred orientation along (110) plane, whereas the morphological studies shows well defined porous structure of the as deposited TiO₂ thin film which can be further utilize for solar cell applications.
