Hybrid structures show improved light emission

Abstract:
New work on hybrid structures containing semiconductor quantum dots and metal nanoparticles could lead to better light-emitting diodes and help develop non-linear photonic devices in the future. So say researchers at Wuhan National Laboratory for Optoelectronics in China and City University of Hong Kong who have studied hybrids made of cadmium telluride quantum dots and gold nanoparticle arrays. The light emitted by the structures can be dramatically increased by simply tuning the surface plasmons on the gold particles to be in resonance with the exciton transitions in the quantum dots.
