Abstract

Structural and spectroscopic characterizations of the Ce ³⁺/Tb ³⁺(Mn ²⁺) solely and Ce ³⁺- Tb ³⁺(Mn ²⁺) doubly doped phosphate compound Ca ₉ZnLi(PO ₄) ₇ with β-Ca ₃(PO ₄) ₂ structure have been performed by powder X-ray diffraction and photoluminescence spectra measurements. The weak green emission from Tb ³⁺ and red emission from Mn ²⁺ are significantly enhanced by introduction of sensitizer Ce ³⁺ ions due to an efficient resonant-type energy transfer from Ce ³⁺ to activators Tb ³⁺ or Mn ²⁺. The energy transfer efficiency and the mechanism have been estimated based on spectroscopic data. Meanwhile, the critical distances for energy transfer between the Ce ³⁺ and Tb ³⁺ or Mn ²⁺ ions are also calculated by the method of spectral overlapping.
