Abstract

The phosphors Ba

SiO

(

=0-0.2

=0-0.15) were synthesized through the solid-state reaction technique. The structure

photoluminescence properties of these phosphors were described. Under the excitation of UV light

the emission spectra of Ba

SiO

show broad band around 384 nm. The emission spectra of Ba

SiO

: Mn

show broad band around 376 nm

and the red emission is very weak. The red emission band located at around 606 nm is strongly enhanced in Ba

SiO

which is arised from

(

G)-

(

S) transition of Mn

. The results show that a part of the energy of Ce

ion is transferred to Mn

ion and sensitizes the luminescence of Mn

ion effectively. When the mole fractions of Ce

and Mn

are 0.2 and 0.075

the red emission around 606 nm is the strongest.
