Abstract

Sub-micron of red phosphor (Y

Gd)BO

: Eu

was prepared by co-precipitation method combined with ultrasonic dispersion. The effects of ultrasonic time on the ion-mixing and the precipitation process

thereby the effect on the performance of powders were studied. The composition

structure and optical properties under VUV were characterized by using infrared spectroscopy (IR)

scanning electron microscopy (SEM)

powder X-ray diffraction (XRD)

PDP VUV phosphor test system. The results showed that groups in (Y

Gd)BO

: Eu

is four-coordinate-based with a mixture of three-coordinate

Gd)BO

is structure of vaterite

the space group is P63/mmc (194)

with cell parameters are

=3.778

=8.814. Comparing the powder prepared by using ultrasonic dispersion in the process of ion mixing and precipitation with the powder prepared by not using ultrasonic dispersion

the relative luminescence intensity increases

color coordinates a red shift (

x=0.639 2

=0.360 4

x=0.642 2

= 0.357 5)

R/O (626 nm/592 nm) increases by 12%

particle size is about 600 nm. And it has a small uniform particle morphology and a good dispersion performance.
