The effects of annealing temperature and time on glassy carbon implanted with 360 keV strontium ions at room and high temperatures are reported. The samples were implanted with strontium ions to a fluence of 2 x 1016 ions/cm2 at room temperatures, 350ºC and 600ºC. The room temperature implanted samples were isochronally vacuum annealed at temperatures from 200ºC to 700ºC for 1 hour. The depth profiles of the implanted samples before and after annealing were obtained by ion beam technique, viz. Rutherford Backscattering Scattering (RBS). Scanning Electron Microscopy (SEM) was employed to investigate the effect of implanted ions and annealing temperatures on the microstructure of the substrate.
