Site-sensitive energy transfer from Ce3+ to Tb3+/Mn2+ based on an efficient phosphor Li4SrCa(SiO4)2:Ce3+
Source abstract
Abstract
Abstract Ce3+,Tb3+/Mn2+ co-doped Li4SrCa(SiO4)2 (LSCSO) phosphors were synthesized by a high-temperature solid-state reaction based on a highly efficient LSCSO:0.03Ce3+ with UV and blue emissions. Energy transfer (ET) in these phosphors was studied. Analyses indicate that ET efficiency from UV Ce3+ to Tb3+ and Mn2+ are larger than that from Ce3+ with blue emission. Different situations in spectral overlap and diverse interactions lead to the different ET efficiency. Emission color of LSCSO:Ce3+,Tb3+,Mn2+ phosphor can be tuned in green-orange-white region by adjusting the concentrations of activators. The present work may provide an example to explore suitable Ce3+ or Eu2+ doped phosphor for single-phase white phosphor on the basis of efficient energy transfer.
