Influence of lanthanide (Gd, Tb or Ce) and silver doping on the luminescence lifetimes of calcium borate investigated by pulsed optically stimulated luminescence

The objective of this work is to evaluate the optically stimulated luminescence (OSL) lifetimes of different polycrystalline CaB6O10:Ln, Agx (Ln = Gd, Tb and Ce; x: % molar concentration) compounds. For the determination of the luminescence lifetimes, time-tagged time-resolved (TTTR) data of the OSL...

Zusammenfassung:	The objective of this work is to evaluate the optically stimulated luminescence (OSL) lifetimes of different polycrystalline CaB6O10:Ln, Agx (Ln = Gd, Tb and Ce; x: % molar concentration) compounds. For the determination of the luminescence lifetimes, time-tagged time-resolved (TTTR) data of the OSL under pulsed stimulation were analyzed. In addition, OSL emission spectra of the samples were recorded to correlate the emission bands with the estimated lifetimes. Whereas single Ce-doped compound presented a fast dominant component (τ
