(FR) MATIÈRE FLUORESCENTE ET PROCÉDÉ DE PRODUCTION DE CELLE-CI
Abstract: front page image
(EN)A fluorescent substance which excels in light-emitting characteristics and versatility, and which can emit light stably, and a lamp using the same are provided at a low cost. Such a fluorescent substance consists of a fluorescent substance which mainly consists of a garnet structure and an element of group V added thereto. Preferably, the fluorescent substance includes a fluorescent substance having a garnet structure in which yttrium • aluminum • garnet (Y3A15O12) is contained as a base component, and further an activator.
(FR)L'invention a trait à une matière fluorescente présentant d'excellentes caractéristiques d'émission lumineuse et de polyvalence et pouvant émettre de la lumière de manière stable, et à une lampe utilisant celle-ci, lesdites matière et lampe étant produites à faible coût. La matière fluorescente comprend une matière fluorescente constituée principalement d'une structure de grenat à laquelle est ajouté un élément du groupe V. De préférence, la matière fluorescente comprend une matière fluorescente comportant une structure de grenat et qui renferme comme composant de base du grenat d'yttrium et d'aluminium (Y3Al5O12) et un activateur.
