| Abstract: | The sodium polyaluminates were synthesized by a high temperature solid state method and the luminescence of Eu2 in the sodium polyaluminates was studied. The results show that the structure of the system Na1 xMgxAl11 -xO17 from x=0.1 t0 x=1 .0 belongs to Na-beta-alumina and the structure of the system Na1.67-2xBaxMg0.67Al10.33O17 changes at about x equal to 0.30, when x is smaller than 0.30 the system forms the solid solution structure of Na-beta-alumina, when x is larger than 0.30 the system becomes the ordered structure of Ba-beta-alumina, correspondingly the emission peak position and the relative emission intensity of Eu2 change with the changes of composition and structure of the system. There exist two kinds of the luminescent centers of high and low energies of Eu2 in the matrix of Na-beta-alumina structure. New phosphor with Ba-beta-alumina structure, Na0.67Ba0.50Mg0.67Al10.33O17:Eu2 , was obtained. |
