Abstract

A series of phosphors Ba

0.955

∶ Eu

(

=0~0.5) were prepared by solid-state reaction in weak reductive atmosphere. The lattice positions and the luminescent mechanism of Eu

in the host were discussed. The effects of B

-substitution on the host lattices and spectral properties were also investigated. It was found that when B

entered BaAl

lattice and substituted for Al

complete solid solutions formed in the whole range of

=0~0.5. The lattice parameters (

) and unit cell volume of phosphors Ba

0.955

∶ Eu

(

=0~0.5) decreased linearly and lattice parameter

increased linearly as boron content increased. A broad excitation spectrum consists of four excitation bands

which locate between 225 nm and 400 nm

its peak wavelength is at 337 nm

and basically does not change with the content of B

. The full width at half maximum is 93 nm. The emission spectrum is also a broad band between 370 nm and 600 nm and its apparent peak is at 437 nm

which can be fitted by two peaks at 423 nm and 457 nm.Two fitted peaks are blue shifted with the increasing of the content of B

-substitution.
