Synthesis, Luminescence and Electronic Band Structure of Al(PO3)3 Crystals

Article Preview

Abstract:

The crystals of aluminium metaphosphate Al(PO3)3 are synthesized by flux method. The photoluminescence properties of Al(PO3)3 are studied under the vacuum ultra violet (VUV) synchrotron excitations. The electronic structure of Al(PO3)3 crystal is calculated by the full-potential linear-augmented-plane-wave (FLAPW) method. The photoluminescence (PL) emission spectra of of aluminium metaphosphate reveal emission bands in the ultraviolet-blue and in the yellow-red spectral regions. Obtained results point to an active role of the electronic states of phosphate groups in the processes of intrinsic luminescence in Al(PO3)3 crystals.
