Optical properties of Zn<inf>2</inf>TiO<inf>4</inf> prepared by thermal oxidation method
Zn-TiO2 thick films were prepared by using thermal oxidation method at 1000°C for 24 h under normal atmosphere, for 0, 10, 20 and 30 mol% of TiO2. The thick films were characterized using XRD, FE-SEM, EDS, and RS. The results indicated that the thick films consisted of hexagonal wurtzite ZnO and fac...

| Summary: | Zn-TiO2 thick films were prepared by using thermal oxidation method at 1000°C for 24 h under normal atmosphere, for 0, 10, 20 and 30 mol% of TiO2. The thick films were characterized using XRD, FE-SEM, EDS, and RS. The results indicated that the thick films consisted of hexagonal wurtzite ZnO and face-center cubic Zn2TiO4 phases, for 10-30 mol% of TiO2. The Zn2TiO4 phase was increased as the increasing of the mol% of TiO2 and became a major phase when TiO2 reached 30 mol%, in distinction with ZnO. The optical energy band gap of thick films was measured by the help of reflection spectra. The optical energy band gap were ranging from about 3.30-3.58 eV, as the mol% of TiO2 increased from 0-30. ©2010 IEEE. |
