“…The decay curve of the green emission at 545 nm under 322 nm excitation conforms to a single-exponential function, while the UCL decay curve conforms to a double-exponential function, which proves that the UCL of Tb-UCMOF involves the energy transfer between the two rare-earth ions. The UCL decay time of the material is 1.8296 ms, which is consistent with the millisecond-level luminescence lifetime results of Tb 3+ in other reports, and the PL decay time is 1.2585 ms. The longer upconverting lifetime is caused by the energy transfer from Yb 3+ to Tb 3+ .…”

“…The 5 D 3 energy level of Tb 3+ is higher than the 7 G 7/2 energy level of Sm 3+ ions, so the energy transfer from Tb 3+ to Sm 3+ is nearly irreversible. 49 Fig. 7 (a) Photoluminescence spectra of SrYMoO co-doped 40%Tb 3+ /10%Sm 3+ under different excitations (b) spectral overlap between the emission spectrum of SrYMoO:40%Tb 3+ and the excitation spectrum of SrYMoO:10%Sm 3+ (c) PL spectra of SrYMoO co-doped 40%Tb 3+ /x%Sm 3+ with (x = 2, 4, 6, 10 mol%) (d) dependence of the Tb 3+ green (548 nm) and Sm 3+ red (598 nm) emissions on the Sm 3+ concentration.…”
