Abstract[English]
A monolithic, vertically integrated, light emitting diode (LED) device (200) for radiative sterilization includes a substrate (202), a deep ultraviolet (DUV) active region (208) located on the substrate (202) and configured to generate DUV light (209), a visible (VIS) active region (220) located on top of the DUV active region (208) and configured to generate VIS light (226), and first and second electrodes (234, 236) configured to inject an electrical current that simultaneously excites the DUV active region (208) and the VIS active region (220) to simultaneously generate the DUV light (209) and the VIS light (226).[French]
La présente invention porte sur un dispositif (200) de diode électroluminescente (DEL) monolithique, intégré verticalement pour stérilisation par rayonnement qui comprend un substrat (202), une région active ultraviolette profonde (DUV) (208) située sur le substrat (202) et conçue pour générer une lumière DUV (209), une région active visible (VIS) (220) située au-dessus de la région active DUV (208) et conçue pour générer une lumière VIS (226), et de première et seconde électrodes (234, 236) conçues pour injecter un courant électrique qui excite simultanément la région active DUV (208) et la région active VIS (220) pour générer simultanément la lumière DUV (209) et la lumière VIS (226).
