New phosphors for white LEDs: Material Design Concepts

Efficient phosphors for white LEDs have been successfully developed, wherein some Material Design Concepts were utilized to promote our research and development effectively and efficiently. Useful ideas for the development of our red and green phosphors, Sr-rich (Sr,Ca,Eu)AlSiN3, (Ba,Eu)3Si6O12N2 and (Ca,Ce)3(Sc,Mg)2Si3O12, are reviewed.
