Abstract (in Japanese) (See Japanese page) 
(in English) Nitridosilicates (Ca,Sr)2(1-x)(Aly,Si1-y)5(O,N)8:Eux are efficient and affordable red-emitting phosphors. In this study in order to improve photodegradation of these phosphors we changed the composition of their alkaline-earth ions and had good results. We also used these phosphors as red-emitting phosphors for white-LEDs and could obtain high CRI successfully.
