The Effect of Band-Gap on TiO2 Thin Film Considering Various Parameters
نویسندگان
چکیده
The aim of this work is to measure the effect band-gap on TiO2 thin films by changing tetrabutylorthotitanate (TBOT), diethanolamine (DEA), and temperature. sol-gel method experimentally introduced find out better varying concentration TBOT (4 ml 10 ml), DEA (2 5 temperature (350°C 650°C). With help an ultraviolet-visible spectrophotometer for wavelength 300-900 nm, these are characterized concerning optical properties (transmittance spectra, absorbance direct band-gap, indirect band-gap). band-gaps found 3.38 eV 3.25 respectively, which close or within standard range (3.2 3.35 eV) at 8 TBOT, 3 DEA, a 550°C.

Tailoring the Energy Band Gap of Transition Metal Doped TiO2 Thin Film
Water splitting for hydrogen production under sunlight using TiO2 as photo catalyst provides a better route for solar energy and attracts the attention of many researchers. The photo catalytic activity of TiO2 under sunlight irradiation depends on the band gap energy. The transition metal doped TiO2 shows an edge over TiO2 in optical absorbance and photo catalytic activity. Thin film of Cr dope...
