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.
