Abstract
We present a Raman-scattering study of damage in O which we have implanted with 90- and 180-keV Cd ions with doses ranging from 1.5 to 1.5× . The Raman scattering was performed prior to annealing in order to study primarily the implantation-produced lattice damage. Using two argon-laser lines close to resonance with the blue exciton, we observe changes from the pure-crystal Raman spectrum at all implantation doses. The unusual sensitivity of the technique can be interpreted in terms of damage-induced broadening of the intrinsic exciton states.
