Abstract
Organic-based photonic crystal (PC) nanocavities emitting in the visible-light range have been demonstrated. Three types of organic layer were used as emitting layers for PCs with emission spectra in the blue, green and red light wavelength ranges. Emission peaks caused by the resonant modes of the PC nanocavities were observed. The wavelength of the peak was controlled by changing the lattice constant of the PC. The emission peaks were observed in the wavelength range of 435 to 747 nm.
