Abstract

Red phosphor (Y

Gd)BO

: Eu

was prepared by coprecipitation method with Y

and H

as the starting material

oxalic acid as precipitant. The effect of the synthetic conditions on the relative luminescence intensity was discussed with orthogonal test. The optimal synthetic conditions were achieved as follows:

oxalic acid

cationic

＝1.2 : 1

pH=8

supersonic time of cation mixing was 20 min

super-sonic time of precipitation was 1 h

calcined temperature was 650 ℃ and the time was 1 h

sintering temperature was 950 ℃ and the time was 2 h. The phosphor was characterized by Vacuum Ultraviolet test system for PDP

XRD and ESEM

respectively. The results showed that the samples exhibited the same diffraction patterns as appeared in JCPDS card No.188-0356 corresponding to the intrinsic diffraction patterns of hexagonal structure of YBO

with the P63/m space group. The average particle size was about 300 nm.
