Thermoluminescence of terbium-doped double fluorides

Electron paramagnetic resonance study of rare-earth related centres in K2YF5:Tb3+ thermoluminescence phosphors

“…, which has a 4f 8 ). In a previous study we, indeed, reported the appearance of very wide and highly anisotropic EPR spectra upon X-ray irradiation of K 2 YF 5 :Tb 3+ [13].…”

“…Recent reports on thermoluminescence (TL) of rare-earth (RE) activated K 2 YF 5 crystals show that these materials exhibit a strong response to various types of ionizing radiation and hence emerge as promising new materials for highly sensitive TL and/or optically stimulated luminescence (OSL) based radiation detectors [1][2][3][4][5][6][7][8][9][10]. The details of the mechanisms of TL and OSL in these systems are, however, not yet fully understood.…”

Investigation on the Thermoluminescence Properties of KGdF4:Sm3+ Polycrystalline

“…Recently, KLnF4 and K2LnF5 (Ln = Gd or Y) crystals doped with trivalent rare earths (e.g. Ce 3+ , Tb 3+ , Tm 3+ and Dy 3+ ions) have been shown to be promising materials for detecting and discriminating different types of radiation fields [1,2,[5][6][7][8][9]. It is known that the thermal neutron absorption cross-sections of 155 Gd and 157 Gd isotopes are 255,000 b and 61,000 b, respectively [2].…”

Structural and Mechanical Properties on Tb3+ Doped KBR Single Crystals

“…The last few decades a lot of luminescence studies have been reported on alkali halides doped with rare earth ions [8,9] . The band gap of alkali halide also has a wide range, varying from 7.34Å for RbI to 4.03Å for LiF [10,11] . In the present work Tb 3+ doped KBr crystals has been grown by Bridgeman Stockbarger method and the grown crystals was subjected to structural, vibrational and mechanical properties.…”
