Abstract:
(EN) Provided is a wavelength conversion member which has superior heat dissipation properties. The wavelength conversion member (100) according to the present disclosure includes a matrix (21) and fluorescent body particles (22) each having a surface layer. The surface layer is a portion from which information about the composition is obtained in energy-dispersive X-ray spectroscopy of the fluorescent body particles (22) at an acceleration voltage of 10.0 kV. The wavelength conversion member (100) satisfies at least one requirement selected from the group consisting of: (a) the fluorescent body particles (22) contain a nitride or an acid nitride as a main component, and the molar ratio of oxygen atoms to all atoms in the surface layer is 20.0% or more; and (b) the fluorescent body particles (22) contain aluminum, and the molar ratio of aluminum atoms to all atoms in the surface layer is lower than the molar ratio of aluminum atoms to all atoms in the fluorescent body particles (22).
(FR) L'invention concerne un élément de conversion en longueur d'onde qui présente des propriétés supérieures de dissipation de la chaleur. L'élément de conversion en longueur d'onde (100) selon la présente invention comprend une matrice (21) et des particules à corps fluorescents (22) ayant chacune une couche de surface. La couche de surface est une partie à partir de laquelle sont obtenues des informations concernant la composition par spectroscopie par rayons X à dispersion d'énergie des particules à corps fluorescents (22) à une tension d'accélération de 10,0 kV. L'élément de conversion en longueur d'onde (100) satisfait à au moins une exigence choisie dans le groupe constitué par : (a) les particules à corps fluorescents (22) contiennent un nitrure ou un nitrure d'acide utilisé comme constituant principal, et le rapport molaire entre les atomes d'oxygène et l'ensemble des atomes dans la couche de surface est supérieur ou égal à 20,0 % ; et (b) les particules à corps fluorescents (22) contiennent de l'aluminium, et le rapport molaire entre les atomes d'aluminium et l'ensemble des atomes dans la couche de surface est inférieur au rapport molaire entre les atomes d'aluminium et l'ensemble des atomes dans les particules à corps fluorescents (22).
(JA) 優れた放熱性を有する波長変換部材を提供する。 本開示の波長変換部材(100)は、表層を有する蛍光体粒子(22)と、マトリクス(21)と、を備える。表層は、10.0kVの加速電圧にて蛍光体粒子(22)のエネルギー分散型X線分析を行ったときに組成の情報が得られる部分である。波長変換部材(100)は、(a)蛍光体粒子(22)が窒化物又は酸窒化物を主成分として含み、表層における、全ての原子に対する酸素原子のモル比が20.0%以上であること、及び、(b)蛍光体粒子(22)がアルミニウムを含み、表層における、全ての原子に対するアルミニウム原子のモル比が、蛍光体粒子(22)における、全ての原子に対するアルミニウム原子のモル比よりも低いこと、からなる群より選ばれる少なくとも1つの要件を満たす。
