摘　　要：The conducting polymer poly (3-methyl thiophene)—P3MT has been comprehensively investigated by electroreflectance (ER), pbotoreflectance (PR), photoluminescence (PL) and: absorption spectroscopics, and the experimental results have been discussed in the light of the theory of fundamental excitation for 1-dimenslonal conducting system. It is demonstrated that the band gap of P3MT is about 2eV and insensitive to the change of temperature. The bipolarons can be induced by doping effect and photo-excitation. The "pinning effect" of ionized dopant and the recombination of exciton have been observed. The microscopic processes of photoelectron transformation in P3MT have been discussed also.The conducting polymer poly (3-methyl thiophene)—P3MT has been comprehensively investigated by electroreflectance (ER), pbotoreflectance (PR), photoluminescence (PL) and: absorption spectroscopics, and the experimental results have been discussed in the light of the theory of fundamental excitation for 1-dimenslonal conducting system.
