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.
