Abstract: A phosphor is provided to ensure excellent luminescent properties when prepared by solid phase synthesis, or luminescent properties usable for white LEDs and controlled particle size and particle shape when prepared by hydrothermal synthesis. A phosphor has a composition represented by the following formula of Na_(X)Eu_(Y)(WO_(4))_(2Z), wherein 1
Abstract translation: 当通过水热合成制备时,提供荧光体以确保通过固相合成制备的优异的发光性质,或可用于白色LED的发光性质和受控的粒度和颗粒形状。 一种荧光体具有由下式表示的Na_(X)Eu(Y)(WO_(4))_(2Z),其中1 <= X <= 5,1 <= Y <= 6, = Z <= 2。 通过水热合成制备NaEu(WO4)2(式中,X = 1,Y = 1和Z = 1)的红色荧光体组合物。 当通过水热合成制备NaEu(WO4)2的红色荧光体组合物时,使用Na 2 WO 4·2H 2 O和Eu 2 O 3作为原料,并以5:0.5-5:3的比例混合。
