Abstract
Series of oxyfluoride phosphors Sr3-xEuxAl1-yByO4-yNyF were prepared by the conventional solid-state reaction. The composition and structure of the Sr3AlO4F∶ Eu3 +could be adjusted by doping BN into the host,and then the luminescence properties of Sr3-xEuxAl1-yByO4-yNyF would be affected. X-ray diffraction( XRD),X-ray photoelectron spectrum( XPS),scanning electron microscopy( SEM),as well as photoluminescence( PL) spectra were utilized to characterize the samples. Under the excitation of UV light,Sr3-xEuxAl1-yByO4-yNyF exhibits the characteristic emissions of Eu3 +,and the luminescence properties of Eu3 +can be enhanced by adjusting doping concentration of BN in the host. The corresponding mechanism has been proposed briefly.
