Abstract

H-PAF(Micro-porous aluminum fluoride)is a porous fluoride with the specific surface area(SSA) of 20-200 m

has a low melting point and high activity characteristics. It can lower the reaction temperature for more than 50℃ and improve the luminescence property of Eu

as a flux. In this paper

H-PAF was used as flux to synthesis Eu

phosphors. The reaction temperature decreased from 1 800℃ to 1 750℃

and the peaks of XRD patterns are more sharp

indicating better crystal crystallization. The white LED device was fabricated using Eu

red phosphor and Ga-YAG green phosphor

and the optical efficiency of Eu

phosphor decreases by about 5% after adding PAF

and the luminous flux of the device increases by more than 2%.
