Theoretical analysis on quenching mechanisms for Lu2O3: Eu3+ nanospheres

Experimental insight into the thermal quenching of the Tb3+ ion’s green photoluminescence in CaWO4 host

“…15) Some possible models were proposed. 15,[21][22][23][24] For instance, in several hosts, there is inter-valence charge transfer between rare earth ions and host, providing an efficient quenching channel for emitting states. 15,21) In fact, there are seven ground states ( 7 F J , J = 0-6) that are close to each other for Tb 3+ ion.…”
