Abstract© 2014 Elsevier B.V. All rights reserved. We report on the enhancement of photoluminescence in thin films of poly[2-methoxy-5-((2′-ethylhexyl)oxy)-1,4-phenylenvinylene], neat or embedded in polystyrene, upon illumination with light as a function of annealing temperature, with our data emphasizing the picture of a light-induced conformation change that leads to the altered photophysical response of this polymer.
