The Te/Pb bilayer samples were prepared by sequential thermal evaporation of Pb and Te on glass substrate. These bilayer samples were irradiated by 100 MeV Ag{sup 9+} at different fluences (3x10{sup 12}, 1x10{sup 13}, and 3x10{sup 13} ions/cm{sup 2}) to synthesis PbTe by ion beam mixing. The samples were characterized by RBS to study composition and X-ray diffraction (XRD) for phase identification before and after irradiation. Thickness of Pb and Te were 75 nm and 105 nm respectively in pristine film as deduced from RBS analysis. The RBS of irradiated sample indicates the mixing between Pb and Te layers. XRD revealed phases of PbTe in sample irradiated at 3x10{sup 13} ions/cm{sup 2}. This phase formation may be due to inter diffusion across the interface induced by swift heavy ion irradiation.
