Preparation of Cr2O3-Ta2O5 Composites Using RF Magnetron Sputtering

Abstract

We prepared Cr2O3-Ta2O5 composite films using our RF magnetron co-sputtering method for the first time. X-ray diffraction (XRD) patterns and photoluminescence (PL) spectra of the films annealed at 700℃, 800℃, 900℃, and 1000℃ were evaluated. From their XRD patterns, the Cr2O3-Ta2O5 film annealed at 700℃ seemed to be almost amorphous, and the one annealed at 800℃ seemed to be hexagonal Ta2O5 doped with Cr. In addition, the Cr2O3-Ta2O5 films annealed at 900℃ and 1000℃ seemed to include tetragonal CrTaO4 phases. Furthermore, it seems that almost no defect exists in our Cr2O3-Ta2O5 composite films annealed at 700℃ - 1000℃ because their PL spectra have no defect-related peak. We thus find that good-quality Cr2O3-Ta2O5 composite films including CrTaO4 can be obtained using our very simple co-sputtering method and subsequent annealing above 900℃.
