摘要

The samples of polycarbonate were implanted to 100 keV Ar⁺ ions at fluences ranging from 1 脳 10¹⁵ to 2 脳 10¹⁶ ions/cm². The effect of ion implantation on DC conductivity and optical behaviour of this polymer has been investigated. The observed changes have been correlated with the induced structural changes in the implanted layer using Raman spectroscopy. The increase in electrical conductivity, decrease in UV-visible transmission and red shifting of the optical absorption edge may be due to the formation of a three dimensional carbonaceous structure having conjugated double bonds in the near surface layer of polycarbonate as a result of ion implantation. The shift in the conduction mechanism in the implanted layer from ohmic towards SCLC has been observed as a function of implantation dose. The novelty of the present study is to investigate the implantation induced electrical conduction mechanism in the implanted polycarbonate and to comprehend it with induced optical behaviour for its utilization as optically active material with conductive surface in various opto-electronic devices.
