Thermoluminescence properties of isostructural K2YF5 and K2GdF5 crystals doped with Tb3+ in response to α, β and X-ray irradiation

Judd–Ofelt analysis of spectroscopic properties of Sm3+ ions in K2YF5 crystal

“…These insights play a key role to improve the existing or to develop new optical devices, such as lasers, light converters, sensors, hole burning high-density memories, optical fibers, and amplifiers. K 2 LnF 5 (Ln = rare earth) crystals doped with rare earth ions are important materials for optical applications such as optical amplifiers and solid-state lasers [1] and especially they are a high energy dosimeter materials of great promise [2][3][4][5]. Recently there are many reports on optical properties of the materials, such as the K 2 YF 5 :Nd 3+ , K 2 YF 5 :Pr 3+ , K 2 YF 5 :Tm 3+ , K 2 GdF 5 :Tb 3+ , and K 2 GdF 5 :Dy 3+ crystals [1][2][3][5][6][7].…”

The authors have investigated the optical properties of these materials by using optically stimulated luminescence (OSL) [8], thermoluminescence [9], frequency upconversion fluorescence [3], site-selective laser-excitation spectroscopy [10].…”

Luminescence characteristics of C 5+ ions and 60 Co irradiated Li 2 BaP 2 O 7 :Dy 3+ phosphor

“…radiation dosimetry. Recently, in this context many well known materials have been investigated using C 6+ , Li 3+ and Ag 12+ ions and found to possess promising properties for dosimetry of heavy charged particles [15][16][17][18][19][20][21][22][23]. In the same context, the present work, describes the carbon and 60 Co induced thermoluminescence properties of Li 2 BaP 2 O 7 :Dy samples.…”

Investigation on the Thermoluminescence Properties of KGdF4:Sm3+ Polycrystalline

“…So far, thermoluminscence (TL) materials based on LiF, CaF2, Al2O3 and CaSO4 have been being used widely for the commercial dosimeter. However, there is always a strong demand in TL phosphors for the measurements of neutron dose in environment and the distinction of radiation field [1,2]. In particular, the traditional TL materials have not responded well to these requirements yet [1][2][3][4].…”

“…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].…”
