Photoluminescence properties of natural sodalite codoped with S_2~- and Eu~(3+)

The orange-colored phosphor powder of natural sodalite codoped with S2-and Eu3+,Na8Al6Si6O24Cl2∶S2-,Eux3+(x=1%,3%,5%,10wt%),were prepared by solid-state reaction method.The sample structure was characterized using XRD.The photoluminescence excitation spectra and the emission spectra at room temperature and low temperature were investigated.The emission spectrum included at 581-625nm originating from the 4f6(5D0)→4f6(7FJ)(J=0,1,2,3,4)transition of Eu3+ and green light at 496nm originating from the 4T1→6A1transition of Mn2+ under 294nm UV excitation.
