Abstract

The polycrystalline samples of K₂BiZr(PO₄)₃ were synthesized by spontaneous crystallization method. The photoluminescence (PL) spectroscopy studies of K₂BiZr(PO₄)₃ are carried out under the VUV synchrotron excitations. The electronic structure of K₂BiZr(PO₄)₃ is calculated by the FLAPW method. The PL spectra of K₂BiZr(PO₄)₃ reveal two main components in the UV and visible spectral regions (peaking near 3.6 and 2.6 eV respectively). It is assumed that the UV PL component of K₂BiZr(PO₄)₃ originates from transitions in ZrO₆ polyhedra, while the visible one is related to Bi³⁺ ions in oxygen coordination.
