Title (EN) SOLID STATE WHITE LIGHT EMITTER AND DISPLAY USING SAME
(FR) EMETTEUR DE LUMIERE BLANCHE A SEMI-CONDUCTEURS ET AFFICHAGE METTANT EN OEUVRE CELUI-CI
Abstract:
(EN) A light emitting assembly comprising a solid state device coupleable with a power supply constructed and arranged to power the solid state device to emit from the solid state device. A series of rare-earth doped silicon and/or silicon carbide nanocrystals that are either combined in a single layer or in individual layers that produce the required Red, Green, and Blue (RGB) emission to form a white light.
(FR) L'invention concerne un ensemble d'émission de lumière qui comprend un dispositif à semi-conducteurs pouvant être raccordé à une alimentation disposée et conçue pour alimenter le dispositif à semi-conducteurs afin que soit produite une émission depuis ce dernier. Une série de nanocristaux de silicium et/ou de carbure de silicium dopés aux terres rares sont combinés en une couche unique ou en couches individuelles qui produisent l'émission rouge, verte et bleue (RVB) souhaitée afin que soit formée une lumière blanche.
