Title (EN) A FIELD EMISSION LIGHT SOURCE ADAPTED TO EMIT UV LIGHT
(FR) SOURCE LUMINEUSE À ÉMISSION DE CHAMP CONÇUE POUR ÉMETTRE DE LA LUMIÈRE UV
Abstract:
(EN) The present invention generally relates to a field emission light source and specifically to a field emission light source adapted to emit ultraviolet (UV) light. The light source has a UV emission member provided with an electron-excitable UV emitting material. The material is at least one of LuPO3:Pr3+, Lu2Si2O2:Pr3+, LaPO4:Pr3+, YBO3:Pr3+ and YPO4:Bi3+.
(FR) La présente invention se rapporte d'une manière générale à une source lumineuse à émission de champ. Plus particulièrement, la présente invention se rapporte à une source lumineuse à émission de champ conçue pour émettre de la lumière ultraviolette (UV). La source lumineuse comporte un élément d'émission d'UV possédant un matériau à émission d'UV excitable par électrons. Le matériau est composé de LuPO3:Pr3+ et/ou de Lu2Si2O2:Pr3+ et/ou de LaPO4:Pr3+ et/ou de YBO3:Pr3+ et/ou de YPO4:Bi3+.
