Description
| - We report on optical-absorption study of Zn1-xMnxO (x=0–0.06) films on fused silica substrates taking special attention to the spectral range of the fundamental absorption edge (3.1–4 eV). Well-pronounced excitonic lines observed in the region 3.40–3.45 eV were found to shift to higher energies with increasing Mn concentration. The optical band-gap energy increases with x too, reliably evidencing strong coupling between oxygen holes and localized spins of manganese ions. In the 3.1–3.3 eV region the optical-absorption curve in the manganese-contained films was found to shift to lower energies with respect to that for undoped ZnO. The additional absorption observed in this range is interpreted as a result of splitting of a localized Zhang-Rice-type state into the band gap.
