The effect of annealing temperature and time on glassy carbon implanted with 360 keV silver at room and high temperatures is reported. The samples were implanted with silver ions at a fluence of 2x10¹⁶ ions/cm² at room temperature, 350 °C, 600 °C and 700 °C. The implanted samples were vacuum annealed for periods ranging from 30 minutes cycles to 12 hours cycles at temperatures from 350 °C to 650 °C. 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 in investigating the effect of implanted ions and annealing on the microstructure of the substrate.
