Photoluminescence - an overview | ScienceDirect Topics
Photoluminescence is a process in which a molecule absorbs a photon in the visible region, exciting one of its electrons to a higher electronic excited state, and then radiates a photon as the electron returns to a lower energy state. www.sciencedirect.com

Luminescent polypyrrole-polymethylmethacrylate (PPy-PMMA) blends have been obtained by bulk polymerization of MMA in presence of different concentration of PPy nanowires. The PPy nanowires are distributed over the rock-like features of PMMA as observed from SEM images. Raman spectra indicate the formation of blend. PPy-PMMA blends exhibit high photoluminescence emission intensity though ...
