Abstract: front page image
(EN)Provided is a fluorescent substance which has excellent chemical stability and has an oxide that shifts the surface electrification characteristics of the fluorescent substance to the positive side and which deteriorates little in luminance. The fluorescent substance comprises a fluorescent-substance base and a composite oxide disposed on at least some of the surface of the fluorescent-substance base, the composite oxide comprising M (M is at least one element selected from a group consisting of Ca, Sr, and Ba), Sn, and O.
(FR)La présente invention a pour objet une substance fluorescente qui possède une excellente stabilité chimique et possède un oxyde qui décale les caractéristiques d'électrification de surface de la substance fluorescente vers le côté positif et qui détériore peu la luminance. La substance fluorescente comprend une base de substance fluorescente et un oxyde composite disposé sur au moins une partie de la surface de la base de substance fluorescente, l'oxyde composite comprenant M (M étant au moins un élément choisi dans le groupe comprenant Ca, Sr, et Ba), Sn, et O.
(JA) 本発明は、化学的安定性に優れ、蛍光体の表面帯電性をプラスシフトさせる酸化物を有する蛍光体であって、かつ輝度劣化が少ない蛍光体を提供する。本発明は、蛍光体本体、及び当該蛍光体本体の表面の少なくとも一部に複合酸化物を有し、当該複合酸化物が、M(MはCa、Sr及びBaからなる群より選ばれる少なくとも1種類の元素)とSnとOとを含む蛍光体である。
