چکیده انگلیسی
In this work, the photoluminescence properties of a PA copolymer, which is a polythiophene derived from 3-OT and (S)-(-)-1-(4-nitrophenyl) pyrrolidin-2-il) methyl 2-(thiophen-3-yl) acetate, were investigated. The optical response of the copolymer dissolved in a toluene solution and of the copolymer film under the optical excitation was analyzed. Besides, the temperature dependence of photoluminescence (PL) of the PA copolymer (solution and film) was examined. The PL behavior of the solution-phase copolymer (diluted and concentrated solutions) under 365 nm (UV light) excitation is reported. Moreover, the copolymer films were obtained using the spin coating technique. The PL of the copolymer films under 488 nm (blue light) irradiation was studied at different excitation powers. Finally, we examined the PL signal temperature dependence of the copolymer film. We determined that the maximum PL signal peak of the copolymer corresponds to 626 nm and has a temperature sensitivity of approximately 11 × 10−3/°C, with a minimum ascending and descending temperature hysteresis between 22 °C and 50 °C.
