Red fluorescent material, method for producing red fluorescent material, white light source, illuminating device, and liquid crystal display
摘要:
The present invention provides an efficient red fluorescent material and a method for producing the same, provides a white light source and an illuminating device each of which uses this red fluorescent material to achieve snow-white lighting, and furthermore provides a liquid crystal display having excellent color reproduction. The red fluorescent material contains an element (A), europium (Eu), silicon (Si), carbon (C), oxygen (O), and nitrogen (N), at an atomic ratio of the following in compositional formula (1). [A(m-x)Eux][Si(9-y)Cy]OnN[12-2(n-m)/3] Note that, in the compositional formula (1), element A is group 2 element including at least calcium (Ca) and strontium (Sr). Also, note that, in the composition formula (1), m, x, y, and n satisfy 3
