Abstract

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. PVK films doped with weight percent varying from 1 to 8 wt% of DCM have been fabricated. The emission spectra are dominated by the presence of DCM and a strong red shift in the emission spectra of the blend has been observed as function of dye concentration. A quenching effect in the excitons lifetime increasing the concentration of the dopants has been observed. These two phenomena have been studied in terms of energy processes inside the blends. © 2013 Society of Plastics Engineers.
