Raman Spectroscopy of Co-Doped ZnO Bulk Crystals

Low-temperature Raman spectra of a bulk mixed crystal Zn1-xCoxO (x = 0.016) are shown and analyzed. Besides the common modes of the ZnO host lattice, electronic transitions related to the presence of Co2+ ions at the Zn sites are observed. In spite of the low Co concentration the presence of collect...

Zusammenfassung:Low-temperature Raman spectra of a bulk mixed crystal Zn1-xCoxO (x = 0.016) are shown and analyzed. Besides the common modes of the ZnO host lattice, electronic transitions related to the presence of Co2+ ions at the Zn sites are observed. In spite of the low Co concentration the presence of collective excitations corresponding to Co and CoO precipitates is also revealed.
