Title
(EN) PHOSPHOR AND LIGHT IRRADIATION DEVICE
(FR) LUMINOPHORE ET DISPOSITIF D'IRRADIATION DE LUMIÈRE
(JA) 蛍光体および光照射装置
Abstract
(EN)
[Problem] To provide a phosphor having a variable wavelength and a light irradiation device having said phosphor. [Solution] This phosphor contains an activating agent, and has a concentration gradient of the activating agent along at least one direction.
(FR)
La présente invention concerne l'obtention d'un luminophore ayant une longueur d'onde variable et d'un dispositif d'irradiation de lumière ayant ledit luminophore. À cet effet, l'invention propose un luminophore qui contient un agent d'activation, et a un gradient de concentration de l'agent d'activation le long d'au moins une direction.
(JA)
