Thermoluminescence of SrB4O7:Dy

Abstract

Subject classification: 78.60.Kn; S10.15The thermoluminescent properties of polycrystalline Dy doped strontium tetraborate are reported. Its efficiency is at least five times larger than that of TLD-700 and therefore comparable to that of Cu doped lithium tetraborate. The isometric plot shows two spectral bands at approximately 480 and 580 nm like the emission spectra of Dy doped phosphors reported to date.

Undoped and calcium doped borate glass system for thermoluminescent dosimeter

“…Borate compounds have been widely studied due to their features as glass formers and also on account of being very advantageous materials for radiation dosimetry applications [1]. These compounds present an effective atomic number which is very close to that of human tissue (Z eff = 7.42).…”

“…Many authors have studied glass and polycrystalline ceramics of alkaline and alkaline earth borate compounds using the thermoluminescence (TL) technique [1][2][3][4][5][6][7][8][9][10][11]. These compounds usually have higher sensitivities when compared to LiF:Mg,Ti (TLD-100) material [1].…”

The influence of annealing temperature and heating rate on thermoluminescence properties of nanocrystalline calcium borate powder

“…Gowda et al [9] had mentioned in his report that radiation interactive characteristics of mixture or compounds that were similar to bone, soft tissue or any other body constituents can be identified for dosimetric purposes. CaB2O4 polycrystalline present a good chemical stability due to their very low hygroscopic nature [10] and linear response with X-ray dose ranges 1 to 1000 mGy and 1 to 10,000 mGy, respectively [11]. The solution combustion method is the among the most popular techniques of production nanocrystals, simple and rapid process.…”

Thermoluminescence, structural and magnetic properties of a Li2O–B2O3–Al2O3 glass system doped with LiF and TiO2

“…Moreover, with the addition of Al 2 O 3 and TiO 2 , chemical durability increases, thus extending its technological applications [5][6][7]. Borate compounds have been shown to be sensitive to ionizing radiation and can be used as TL dosimeters, especially because they have an effective atomic number close to that of human tissue (Z eff ¼ 7.42) and generally exhibit higher sensitivity than the TLD-100 dosimeter [8][9][10][11][12][13].…”
