Photoluminescence of Pyrrole Oxidized in Hydrogen Peroixde
The optical absorption and photoluminescence (PL) of 5-(2-pyrrolyl)-2-pyrrolidinone were investigated with ultra-visible absorption spectroscopy and photoluminescence spectrscopy. Upon the 325 nm excitation from a helium-cadmium laser, strong blue PL was recorded for the 5-(2-pyrrolyl)-2-pyrrolidinone. The peak of the PL was located at about 425 nm (2.92 eV). The origin of the strong PL can be assigned to isolated carbonyl group.
