Abstract

Strontium aluminates doped with europium and dysprosium have been attracting people's attention for their great stability

high quantum transformation rate and fine luminescence performance. The preparation and spectra properties of yellow-green phosphor SrAl

:Eu

and blue-green phosphor Sr

:Eu

are commonly researched while those of SrAl

:Eu

is rarely studied. In this paper

SrAl

:Eu

violet fluorescent powder was synthesized using SrCO

and Al

as raw materials employing high temperature solid-state reaction

whose emission spectrum located at 395nm. The crystal structure was analysised by X-ray diffraction(XRD) when n

=1:12. The XRD results suggested the characteristic peaks of Sr

gradurally decreased while those of SrAl

increased by degrees when reaction temperature rised from 1150℃ to 1250℃. That's to say

the change of reaction temperature brought about the transformation of crystal structure. The excitation and emission spectra were tested by fluorescence spectrophotometer. When the reaction temperature was 1150

1200

1250℃ respectively

the ratio of Sr and Al differed from 1:6 to 1:18 in order to investigate the corporate effect of matrix composing and reaction temperature on spectra properties. According to the binary phase diagram of SrO and Al

the lower of SrO content and the higher of Al

content

the higher of the reaction temperature of corresponding strontium aluminates. With the content of Al in matrix increasing and reaction temperature rising

the transformation of crystal structure might change the crystal field environment

leading to the variety of emission spectra. The emission spectra shifted from 490nm to 395nm. The luminescence intensity of SrAl

:Eu

t to be the strongest under the condition that n

=1:12 and reaction temperature was 1 250℃. The decay curve investigation was also tested in fluorescence spectrophotometer

which showed SrAl

:Eu

has no afterglow performance

which may correspond with the spinel structure of SrAl

. The preparation and spectra properties of SrAl

:Eu

violet fluorescent powder were studied. The effect of reaction temperature and the matrix composing on crystal structure and emission spectra was investigated. The research may be helpful for correlative workers.
