SiC FLUORESCENT MATERIAL, METHOD FOR PRODUCING SAME AND LUMINESCENT ELEMENT

摘要

Provided are a SiC fluorescent material with improved luminous efficiency, a method for producing the same and a luminescent element. A fluorescent material in which the carbon atom is composed of a SiC crystal disposed in a cubic site and a hexagonal site and to which a donor impurity and an acceptor impurity are added, wherein the ratio of the donor impurity that is substituted with the carbon atom in the cubic site with respect to the donor impurity that is substituted with the carbon atom in the hexagonal site is greater than the ratio of the cubic site with respect to the hexagonal site in the crystal structure.
