Patent

CA 2620558

The invention relates to a luminescent substance consisting of a doped host lattice which absorbs at least one part of exciting radiation whet it is excited by a high-energy exciting radiation, thereby releasing an energy-poor emission radiation. According to said invention the host lattice is embodied in the form of a carbidonitridosilicate-based compound. An illuminant which is used for producing white light and comprises a light emitting element and said luminescent substance are also disclosed.

La présente invention concerne une substance luminescente constituée d'un réseau hôte dopé qui absorbe au moins une partie d'un rayonnement d'excitation lorsqu'il est excité avec un rayonnement d'excitation de grande énergie, libérant ainsi un rayonnement d'émission plus pauvre en énergie. Selon cette invention, le réseau hôte est un composé à base de carbidonitrilosilicate. Cette invention concerne également un système lumineux qui est conçu pour produire de la lumière blanche et qui comprend un élément émetteur de lumière et la substance luminescente susmentionnée.
