Effect of 200 keV Ar~+ Implantation on Optical Electrical Properties of Polyethyleneterepthalate (PET)

摘要

In the present paper we have discussed the effect of 200 keV Ar~+ ions on the electrical and optical properties of PET samples. PET samples were implanted with 200 keV Ar~+ ions to various doses ranging from 1×10~(15) to 1×10~(17) Ar~+ cm~2. The changes in the electrical and optical properties of pristine and implanted PET specimens have been studied by using Keithley electrometer and UV-Visible absorption spectroscopy. The electrical conductivity has found to be increased with increasing ion dose. The optical studies have revealed the drastic alterations in optical band gap from 3.63 eV to 1.48 eV and also increase in number of carbon atoms per cluster from 215 to 537. Further, the change in the electrical conductivity and optical band gap has also been correlated with the formation of conductive islands in the implanted layers of PET.
