A new method for tuning and enhancing photoluminescence characteristics of light emitting poly (3-methylthiopnehe) (P3MT) nanotubes through electron (E)-beam irradiation under atmospheric environments is reported. From laser confocal microscope photoluminescence (PL) experiments, significant enhancements in PL intensity are observed. The luminescent color of the P3MT nanotubes changed from green to red depending on the variation of E-beam dosage, originated from the de-doping effect and the conformational modification through E-beam irradiation.
