Author Affiliations +
Abstract
Raman and photoluminescence spectra were obtained from diamond and diamondlike carbon films synthesized by plasma enhanced CVD techniques. Depending upon certain synthesis conditions, films exhibited photoluminescence attributed to the GR1 color center known to occur in irradiated natural diamond crystals. Photoluminescence intensity, corresponding to the GR1 centers, increased with increasing diamond content of the films, both in terms of film thickness and ratio of diamond to graphitic bonding.
