OPTICAL PROPERTIES OF V2O5:TIO2 THIN FILM PREPARED BY PLD TECHNIQUE
In this work, pure and doped Vanadium Pentoxide (V2O5) with TiO2 of different ratios (0, 0.1 , 0.3, 0.5) wt were obtained using Pulse laser deposition technique on amorphous glass substrate with thickness of (250)nm at T=373k. The morphological, UV-Visible was studied. The Transmittance and Absorption of each Film, in the spectral range (300 to 1100) nm, were measured from which the optical constants (Refractive index, Absorption coefficient, Extinction coefficient and Energy gap) were determined .The energy band gap of the films was found to be change from (2.44 to 4.07) eV when the concentration of TiO2 increases from (2.66 to 4.07 ) eV The results showed a significant improvement in the transmittance and refractive index in TiO2 doped V2O5 thin films .All measured values were in consistent with other previous studies.
