TL and OSL study of Li2B4O7:Cu,Ag synthesized by combustion and solid-state reactions
Brazilian Journal of Radiation Sciences, 2022 The aim of this work was to investigate the Thermoluminescence (TL) and the Optically Stimulated Luminescence (OSL) responses of Li2B4O7: Cu, Ag synthesized using two method: a) solid-state and b) liquid combustion methods. In both procedures 0.4% mol of

Simulation of optically‐stimulated luminescence of zircon [PDF]
physica status solidi c, 2007 AbstractMineral zircon, ZrSiO4, belongs to a class of materials that can be used as a chronological tool in geology and archaeology for measurements of the natural radiation dose and the sample age by optical methods. The model of optically stimulated luminescence developed earlier is used to investigate the applicability of the single‐aliquot ...

DUST EFFECT ON OPTICALLY STIMULATED LUMINESCENCE DOSIMETRY [PDF]
RAD Conference Proceedings, 2017 Optically stimulated luminescence dosimetry (OSLD) has been used for dose measurements in many different radiation fields for personal monitoring and medical and industrial applications. One of the most important advantages of the OSLD compared to thermoluminescence dosimetry (TLD) is the light source used to stimulate the crystal.

Effect of Sr on the luminescence properties of Eu3+ activated xZnO-(1-x) SrO-Al2O3 phosphors
Materials Research Express, 2020 Europium-doped xZnO-SrO-Al _2 O _3 (x = 0, 0.2, 0.4, 0.5, 0.6, 0.8, 1) phosphors were synthesized by the traditional Solid-State Reaction (SSR) method. The structure of the phosphors prepared was analysed with the x-ray diffraction technique. The xZnO-(1-
