Abstract

Series of oxyfluoride phosphors Sr

F were prepared by the conventional solid-state reaction. The composition and structure of the Sr

AlO

F:Eu

could be adjusted by doping BN into the host

and then the luminescence properties of Sr

F 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

F exhibits the characteristic emissions of Eu

and the luminescence properties of Eu

can be enhanced by adjusting doping concentration of BN in the host. The corresponding mechanism has been proposed briefly.
