A resonance Raman scattering study is presented of the annealing behavior of Cu2O implanted with 180hyphen;keV Cd++ions to a dose of 1times;1014ions/cm2. As annealing progressed, large changes were observed in the Raman spectra which were obtained with the 488hyphen; and 476.5hyphen;nm lines of an argon laser to provide excitation nearly resonant with the 1S rsquo;rsquo;bluersquo;rsquo; exciton at 480 nm. A detailed comparison is made of the spectra obtained during annealing with spectra previously reported on unannealed samples implanted with doses ranging from 1.5times;1011to 1.5times;1015ions/cm2. The analysis indicates a strong annealing stage at minus;250deg;C, after which apparently less than 1percnt; of the implantationhyphen;produced damage remains.
