Disclosed is a phosphor having enhanced luminance. Specifically disclosed is a phosphor characterized by being substantially composed of an oxide containing Sr, Ca, Eu, Mg, Si and a halogen element(s) at a molar ratio of a:b:c:d:e:f (wherein a is not less than 0.5 but less than l, b is not less than 0 but less than 0.5, c is more than 0 but less than 0.3, d is not less than 0.8 but not more than 1.2, e is not less than 1.9 but not more than 2.1 and f is not less than 0.0008 but not more than 0.3), which oxide further contains oxygen.
本发明公开了一种具有更高亮度的荧光粉。具体地说,公开了一种荧光粉,其特征是基本上由含有 Sr、Ca、Eu、Mg、Si 和卤素元素的氧化物组成,其摩尔比为 a:b:c:d:e:f(其中 a 不小于 0.5 但小于 l,b 不小于 0 但小于 0.5,c 大于 0 但小于 0.3,d 不小于 0.8 但不大于 1.2,e 不小于 1.9 但不大于 2.1,f 不小于 0.0008 但不大于 0.3),该氧化物还含有氧。
