荧光物质、发光器件以及用于生产荧光物质的方法
Abstract:
本发明涉及荧光物质、发光器件以及用于生产荧光物质的方法具体地，根据本发明的荧光物质在具有250到500nm波长范围内的峰值的光的激励下发出具有500到600nm波长范围内的峰值的荧光，所述荧光物质在560nm具有4×10-5或更小光吸收系数α560nm。该物质通过下列公式(1)来表示：(M1-xCex)2yAlzSi10-zOuNw(1)。在该公式中，M是从由Ba、Sr、Ca、Mg、Li、Na和K构成的组中选择的金属元素；而x，y，z，u和w是分别满足下列条件的变量：0＜x≤1，0.8≤y≤1.1，2≤z≤3.5，u≤1，1.8≤z-u以及13≤u+w≤15。
Abstract(English):

The invention relates to a fluorescent substance, a light-emitting device and a method for producing the fluorescent substance. The fluorescent substance according to the present disclosure emits luminescence with a peak in the wavelength range of 500 to 600 nm under excitation by light with a peak in the wavelength range of 250 to 500 nm, and has an optical absorption coefficient alpha 560nm of 4*10 -5 or less at 560 nm. The substance is represented by the following formula (1): (M 1-xCex) 2y AlzSi 10-zOuNw (1). In the formula, M is a metal element selected from the group consisting of Ba, Sr, Ca, Mg, Li, Na and K; and x, y, z, u and w are variables satisfying the conditions of 0
