Abstract :
A new nanocomposite material was created by embedding colloidal CdSe-based quantum dots (QDs) within single crystal nanoporous gallium nitride (GaN) host. High efficiency luminescence and wavelength-engineered ability of colloidal QDs combined with high performance of nitride blue LEDs suggest this nanomaterial´s potential for solid state lighting.
