description	[Problem] The objective of the present invention is to provide a dimming agent and a light-emitting device, capable of limiting brightness without lowering the current value of a current being injected into an LED. [Solution] The invention is the dimming agent having a diffuse reflection intensity of 80% or lower at wavelengths from 400 nm to 750 nm, characterized by containing at least one among terbium, praseodymium, manganese, and titanium. Le problème à résoudre par la présente invention est de fournir un agent de gradation et un dispositif électroluminescent, pouvant limiter la luminosité sans abaisser la valeur de courant d'un courant qui est injecté dans une DEL. La solution selon l'invention porte sur un agent de gradation ayant une intensité de réflexion diffuse inférieure ou égale à 80 % à des longueurs d'onde de 400 nm à 750 nm, caractérisé en ce qu'il contient au moins un composant parmi le terbium, le praséodyme, le manganèse et le titane. 【課題】　ＬＥＤへ注入する電流の電流値を低くすることなく、明るさを抑えることができる減光剤及び発光装置を提供することを目的とする。【解決手段】　テルビウム、プラセオジム、マンガン、チタンのうち少なくとも１つを含むことを特徴とする、波長４００ｎｍから７５０ｎｍの拡散反射強度が８０％以下の減光剤。
