Abstract

Studies on the crystal structure and luminescence properties have been performed for the NaPr1−xCexP4O12 polyphosphate series. Excitation and emission spectra of Pr3+ and Ce3+ luminescence from NaPrP4O12:Ce3+ clearly reveal an efficient Pr3+  → Ce3+ energy transfer via migration over the Pr3+-sub-lattice and a nonradiative resonant transfer to the Ce3+ ions. Analysis on scintillation characteristics of the NaPr1−xCexP4O12 series shows a maximum light yield of 11 000 ± 1000 ph MeV−1 for NaPr0.99Ce0.01P4O12, proving the studied polyphosphates to be promising for application in the detection of x-ray and gamma quanta.
