Raman scattering in ZnMnO prepared by ion implantation

ZnMnO has been successfully prepared by high-dose Mn implantation into ZnO crystal. The influence of implantation and annealing on ZnMnO Raman spectra has been investigated. The E/sub 2/ mode weakens, broadens and red-shifts after the implantation, while the A/sub 1/(LO) mode intensifies, broadens and red-shifts. After thermal annealing a new mode at 528 cm/sup -1/ shows up. With the recursion method calculation this new mode is attributed to the softening of Zn-O vibration caused by Mn incorporation.
