Tb3+-Tb3+ cross-relaxation study under novel experimental technique: Simultaneous laser excitation at UV–Vis

Structure–Activity Optimization of Luminescent Tb-doped LaF3 Nanoparticles

“…These emission bands are reported in the literature for low Tb concentration in Tb-doped materials, and for higher Tb contents, their intensity decreases due to Tb−Tb cross-relaxation energy transfer (CRET) along with the increase of green emission bands. 30,31 Unfortunately, the contribution of CRET as a function of the Tb doping rate cannot be investigated here, as the emission from the 5 D 3 level is not visible under our conditions.…”

Energy Transfer and Temperature Measurement Performance for NaGd(1-x-y)TbxEuySiO4 Phosphor

“…Emission peaks appear at 493, 546, 599 and 624 nm, responding to the transitions of 5 D 4 → 7 F 6 , 7 F 5 , 7 F 4 and 7 F 3 , respectively. 28,29 Figure 3b shows the Tb 3+ emission intensity vs doping concentration. With the gradual growth of the concentration of Tb 3+ from 10 mol% to 50 mol%, the emission intensity keeps increasing, and the locations and shapes of the emission peaks do not alter significantly.…”
