Abstract

The Infrared- and Raman-spectra of the intermediate compounds were studied for clues to their structural behavior as related to luminescence response. It was found that the degree of polymerization of PO4 polyhedra increases in the phosphate-rich region and perhaps in the RE-oxide-rich region as well which was evident from the shift of stretching bands towards the higher energy side. Except in orthophosphates, the PO4 polyhedra occupy more than one non-equivalent lattice site in all the phosphates.
