In this work, the photophysical proprieties of 4-(dicyanomethylene)-2- methyl-6-(p-dimethylaminostyryl)-4H-pyran (DCM) dye in the poly-vinylcarbazole (PVK) matrix are analyzed with a particular attention to the energy transfer processes between the matrix and the dye. PVP films with varying weight percent (from 1 to 8 wt%) of DCM have been fabricated. The presence of DCM induces a red shift in the emission spectra of the blend and a quenching effect in the excitons lifetime increasing the concentration of the dopants. These two phenomena have been studied in terms of energy processes inside the blends. © 2012 American Institute of Physics.
