Abstract

A composite of the conjugate conductive polymer poly(2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene) (MEH-PPV) and CdSe/ZnS quantum dots (QDs) is utilized for nanoimprinted lasers after drop-casting onto one-dimensional omnidirectional Bragg mirrors. Strong amplified spontaneous emission is observed at the resonances of both the QDs and the polymer. Clearly resolved, low-threshold lasing was found after nanoimprinting of distributed-feedback gratings on the composite surface. Energy transfer between the polymer molecules and the QDs is demonstrated by excitation spectroscopy.
