Abstract
A new host structure of YAG/Ce phosphor is obtained by the addition of Si in the form of Si3N4Si3N4 . The emission spectrum shows blue shift with lower emission intensity due to the changes in coordination environments of the whole crystal structure. Based on the results of Al27Al27 solid-state nuclear magnetic resonance measurements of YAG∕Ce+xSi3N4YAG∕Ce+xSi3N4 , we propose that the Si4+Si4+ ions are the major substituent into the host structure which is further identified by X-ray diffraction patterns.Keywords
