摘要: Abstract The energy transfer (ET) between Eu2+ and Mn2+ in Ca5(PO4)3Cl has been investigated. At low intensities under 405 nm excitation, time-resolved experiments provide microscopic parameters for the adjacent ions. high intensities, we observe a non-linear component process due to ground state depletion of ions, leading not reduction, but an increase rate ions also excited This results sub-linear response both luminescence as function intensity. Our observations are quantitatively described by model using state.
