Electrical and Optical Properties of Air-stable, Iodine-doped Natural Cotton Fibers
A. S. Zakirov,율다세프,조학동,전희창,강태원,A. T. Mamadalimov 한국물리학회 2014 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.64 No.4
The influence of sodium-hydroxide treatment and iodine doping on the optical and the electricalproperties of cotton fibers is investigated by using photoluminescence (PL), as well as photoconductivity,measurements. The iodine doping results in a quenching of the PL and an enhancement ofthe photoconductivity due to the photo-induced charge transfer between the dopants and the cottonfibers. The conductivity of the iodine-doped cellulose fibers shows a significant enhancement bymore than five orders of magnitude as compared to that of the undoped samples. A good correlationis found between the changes in the fiber’s morphology and the electrical and optical properties ofthe fiber, which opens interesting perspectives for molecular donor-acceptor device applications.
