Two-dimensional GaN films and ribbons have been synthesized within Na-4 mica nanochannels. The thickness of the films is 0.6 nm as estimated from published x-ray diffraction data of Na-4 mica. Room temperature photoluminescence studies show a blue shift in bandgap which is ascribed to the quantum confinement effect. Unusually long excitonic lifetimes in these 2D systems appear to indicate low density of defects.
