RED PHOSPHOR, PRODUCTION METHOD FOR RED PHOSPHOR, WHITE LIGHT SOURCE, ILLUMINATION DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Provided are: a highly efficient red phosphor and a production method for same; a white light source and an illumination device that are capable of pure white illumination by using the red phosphor; and a liquid crystal display device with good color reproduction properties. An element (A), europium (Eu), silicon (Si), carbon (C), oxygen (O), and nitrogen (N) are contained in the atomic ratios shown in compositional formula (1). (In compositional formula (1), element A is an element from Group 2 which includes at least calcium (Ca) and strontium (Sr). In addition m, x, y, and n fulfill the relationships 3
