Abstract

The photoluminescence properties of undoped Al(PO₃)₃ crystals synthesized by flux method are studied under VUV synchrotron excitations. The electronic structure of Al(PO₃)₃ crystals is calculated by the FLAPW method. The PL emission spectra of Al(PO₃)₃ reveal emission bands in the violet 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.
