Production method of the illuminant and the aforementioned fluorescent substance which possess the fluorescent substance of red luminous characteristic Sr2Si5N8 type and the fluorescent substance which catches

摘要

The new fluorescent substance designates the class of nitoridoshiriketo as the foundation, is doped desirably with Eu. As for the aforementioned fluorescent substance, Eu which is improved ^{alkaline earths nitoridoshiriketo MSiN which is doped _{[in formula, as for M, it is the element of 1 kinds or more from the group of Sr, Ca and Ba] being, at that time, as for aforementioned nitoridoshiriketo, it has been stabilized by the oxide phase or okishinitorido phase of alkaline earths content.}}
