Photoluminescence and thermally-stimulated luminescence (TSL) characteristics of BaCaBO 3 F doped with various amounts Tm were evaluated. The Tm-doped showed an emission a sharp peak around 460 nm originating from the 4f-4f transition 3+ in photoluminescence scintillation. Their scintillation decay times for 0.68–0.73 1.28–1.55 ms, respectively. Furthermore, TSL dynamic range glow peaks at 190 ...

Three equal-depth traps reported in NaCl have been attributed to different defect configurations. In this trio system, the basic trap configuration proposed is bi-vacancy, analogy being drawn through observations KCl crystal. Two other configurations that emerged are derivatives of bi-vacancy with next nearest neighbor I-V pair and VF center which represents a hole linked cation vacancy.

Abstract Archaeological ceramics are considered one of the most important sources both technological and chronological information. Here, investigation some archaeological underwater amphorae from Egadi’s Battle, that decided end First Punic War (241 B.C.), is reported. X-ray Diffraction (XRD), Fluorescence (XRF), petrography, Thermoluminescence (TL) were used to determine composition evaluate ...
