We present measurements of absorbance and photoluminescence (PL) for films of poly­(3-(2,5-dioctylphenyl)­thiophene) (PDOPT) as a function of temperature (T) and time (t) of illumination. While having no detectable influence on absorbance of this conjugated polymer, our experiments clearly revealed...
