摘要：

Transparent polycarbonate samples were implanted with 1 MeV Ag+ ions to various doses ranging from 5 x 10(14) to 3 x 10(16) ions cm(-2) with a beam current density of 900 nA cm(-2). Modification in the structure of polycarbonate as a function of the implantation fluence was investigated using micro-Raman spectroscopy, glancing angle X-ray diffraction, and UV-Vis spectroscopy. Raman spectroscopy pointed toward the formation of graphite structures/clusters due to the ion implantation. UV-Vis absorption analysis suggests the formation of a carbonaceous layer and a drastic decrease in optical band gap from 4.12 eV to 0.50 eV at an implanted dose of 3 x 10(16) ions cm(-2). The correlation between the decrease in band gap and the structural changes is discussed.
