Abstract

SiO

(ZnB

) ∶ Mn

phosphors was fabricated by solid reaction method. The influences of sintered temperature and Sm

content on the luminescence properties of Zn

SiO

(ZnB

) ∶ Mn

phosphors were studied. Powder structure and luminescence properties were characterized by means of XRD

excitation and emission spectra. The experimental results indicate that Zn

SiO

(ZnB

) ∶ Mn

has two excitation peaks at 220 nm and 250 nm

the luminescence intensity is the largest when the sintered temperature is at 950 ℃ in reducing atmosphere

and the emission peaks at 521 nm. The ZnB

as a part of host produced in the reaction can improve the luminescence intensity. At 950 ℃

there are most ZnB

reaction products

meanwhile

ZnB

has the best crystalline properties. With the Sm

content increased

the phase is not changed

however

to a large extent

the luminescence intensity can be improved. When the Sm

mole fraction is 8%

the intensity is the most and 5 times stronger than that for 4% Sm

. With the increasing of Sm

mole fraction

the luminescence emission peak has blue-shift from 540 nm to 521 nm.
