Abstract:
(EN) This wavelength converting member (2) comprises: a wavelength converter (10) including a resin (12) and a fluorescent colorant (15) dispersed in the resin; and an oxygen gas barrier layer (20) that covers at least a portion of the surface of the wavelength converter (10), and that suppresses the intrusion of oxygen into the wavelength converter (10). The oxygen gas barrier layer (20) is made of a silica glass (21) employing, as a precursor, a polysilazane and/or a polysilazane derivative.
(FR) Selon la présente invention, cet élément de conversion de longueur d'onde (2) comprend : un convertisseur de longueur d'onde (10) comprenant une résine (12) et un colorant fluorescent (15) dispersé dans la résine ; et une couche barrière contre les gaz oxygène (20) qui recouvre au moins une partie de la surface du convertisseur de longueur d'onde (10), et qui supprime l'intrusion d'oxygène dans le convertisseur de longueur d'onde (10). La couche barrière contre les gaz oxygène (20) est constituée d'un verre de silice (21) utilisant, en tant que précurseur, un polysilazane et/ou un dérivé polysilazane.
(JA) 本発明の波長変換部材(2)は、樹脂(12)とこの樹脂中に分散した蛍光色素(15)とを有する波長変換体(10)と、波長変換体(10)の表面の少なくとも一部を被覆し、波長変換体(10)中への酸素の侵入を抑制する酸素ガスバリア層(20)と、を備え、酸素ガスバリア層(20)は、ポリシラザン及びポリシラザン誘導体の少なくとも一方を前駆体とするシリカガラス(21)からなる。
