Abstract

The phosphors composed of Eu or Ce ions doped in Ba

(PO

)

(SiO

)

matrix were prepared by solid state reaction. The PL spectra properties of Ba

(PO

)

(SiO

:Eu

and Ba

)

(SiO

)

:Ce

were investigated. Strong broad excitation band was observed in both samples. The Eu

of Stokes shift (

) and excitation energy of Ba

(PO

)

(SiO

)

:Eu

were calculated by the PL spectra of Ba

(PO

)

(SiO

)

:Ce

. The estimated excitation energy and the experiment result are closely coincided. Ba

(PO

)

(SiO

)

:Eu

can be excited by UV-LED or blue LED

and emits absinthe-green light.
