Abstract

doped Ba

(PO

)

Cl(

5)blue phosphors particle were prepared by the conventional solid-state reaction method. It can be clearly exhibited that XRD peaks of the samples shift to the smaller angle side with the increasing content of Ba

.In excitation spectra

two peaks fell toward each other of all the samples and their intensities decreased with increasing content of Ba

which can be explained by the configuration-coordinate model. Seen from the emission spectra

the position of the emission peaks did not change with the excitation wavelengths

which indicated that two emission peaks did not come from two different sites of Eu

ions. It can be attributed to two Stark levels of 4f

configuration. The broader emission bands can be attributed to the increase of inhomogeneous line width from changed crystal field by introducing Ba

ions. The excitation and emission spectra show that Eu

doped Ba

(PO

)

Cl is a promising blue phosphor for ultraviolet light emitting diode (LED).
