Growth and Raman spectra of doped ZnO single crystals

ZnO:Mn+(Mn+ = Cd2+, Co2+, Ni2+, Sc3+, In3+, Ga3+, Fe3+, Te4+, V5+) single crystals have been grown under hydrothermal conditions in ZnO-MxOy-KOH-LiOH-H2O systems, and their Raman spectra have been measured under visible (514.5 nm) and near-IR (1064 nm) excitation. The anomalous band between 500 and 600 cm−1 in the Raman spectra of ZnO:Mn2+ has A1 symmetry and is due to vibrations involving Mn2+.
