摘要：
Provided are phosphors that can provide emission devices that can further improve emission characteristics, principally, color rendering. Disclosed are phosphors made by substituting at least a portion of M2 in compounds represented by Formula (1) with M4 (M4 represents a trivalent cationic element), substituting a portion of O in said compound with M5 (M5 represents a trivalent anionic element) and substituting a portion of M1 and/or M2 in said compound with an activated element. In Formula (1): aM1O.3M2O.6M3O2 (In Formula (1), M1 represents one or more alkaline-earth elements selected from a group comprising Ba, Sr and Ca, M2 represents one or more divalent metal elements selected from a group comprising Mg and Zn, M3 represents a tetravalent metal element and a is a value in the range 3 to 9.)
