“…The time constant of the rise of pressure, life time of the interacting F centres or damping time of dislocation segments and the activation energy can be determined from the ML measurements. We have also, reported the increase in luminescence (TL, ML and LL) intensity by addition of rare earth impurity in alkali halides based materials [28][29][30][31].…”

The thermoluminescence (TL) characterizations of γ-irradiated KCl:Dy phosphor for radiation dosimetry are reported. All phosphors were synthesized via a wet chemical route. Minimum fading of TL intensity is recorded in the prepared material. TL in samples containing different concentrations of Dy impurity was studied at different γ-irradiation doses. Peak TL intensities varied sublinearly with γ-ray dose in all samples, but were linear between 0.08 to 0.75 kGy for the KCl:Dy (0.1 mol%) sample. This material may be useful for dosimetry within this range of γ-ray dose. TL peak height was found to be dependant on the concentration (0.05-0.5 mol%) of added Dy in the host.

Ce 3+ , Sn 2+ )-codoped NaCl phosphor was synthesized from an aqueous solution of NaCl−CeCl 3 −SnCl 2 . The synthesized NaCl:Ce 3+ , Sn 2+ phosphor was examined using X-ray diffraction analysis, photoluminescence (PL) analysis, PL excitation spectroscopy, and PL decay measurements. The Sn 2+ emission band peaking at ∼530 nm was enhanced about four times compared to that without adding Ce 3+ donor ions. The enhanced PL intensity was understood to be due to an energy transfer from Ce 3+ to Sn 2+ in the NaCl host. The energy transfer efficiency was estimated from the Sn 2+ acceptor concentration dependences of the Ce 3+ donor emission intensity and average decay time in the NaCl:Ce 3+ , Sn 2+ phosphors.
