The fluorescence behaviour of Gd3+ and Tb3+ was studied with the ions dissolved together in a calibo-1 glass host. The two ions from a coupled system so that energy absorbed by Gd3+ is transferred to Tb3+ by a nonradiative mechanism and is then emitted as Tb3+ fluorescence. When Tb3+ incorporated alone into this glass, concentration quenching effects are observable.
