Abstract:
A light-emitting device comprises a light source in the form of an incandescent filament, a substantial part of which is integrated in a host element having at least one portion structured according to nanometric dimensions. The nano-structured portion is in the form of a photonic crystal or of a Bragg grating for the purpose of obtaining an amplified or increased emission of radiation in the region of the visible.
