Thermoluminescence studies on alkali-silicate glass doped with dysprosium oxide for use in radiation dosimetry measurement

Physical properties and thermoluminescence of glasses designed for radiation dosimetry measurements

“…Therefore, the ions of CeO 2 , Nd 2 O 3 and MnO 2 play important roles in improving the sensitivity and response to radiation dose of glass samples by trapping the excited electrons from X-ray irradiation. To be more accurate, the SiO 4 groups, irradiated with X-rays are changed to [SiO 3 The mechanism of this process can be represented as reaction [8]:…”

“…It comprises more than 10% by mass of the earth's crust. Many researchers around the world have investigated the properties of glass materials such as elastic moduli, optical, radiation and electrical for design and development in many applications including laboratory, industrial, medical, nuclear waste disposal, radiation dosimetry and communication technology [1][2][3][4][5][6][7][8]. Mechanical and physical properties of glasses are determined by the composition of the material and preparation techniques.…”

“…New series materials are now being improved with more sensitivity and linearity of TL output in a wide range of doses. Some types of glasses, doped with small concentrations of rare-earth ions (ROs) and/or transition metal ions (TMOs) as activators have been found to be very effective [8,16,17]. Thermoluminescence glass materials doped with ROs and/or TMOs now play important roles in the field of radiation detection (both basic and applied research) including nuclear power generators, radiation oncology, personal and environmental monitoring and geological dating.…”

Effect of gamma ray irradiation on sodium borate single crystals

“…Chen's peak shape method can be utilized to calculate the trap parameters (Daniel et al, 2014;Laopaiboon et al, 2015;Som et al, 2015;Shrivastava et al, 2014). This method is useful for a broad range of activation energies in the range 0.1 eV to 2.0 eV and frequency factor between 10 5 s -1 to 10 23 s -1 .…”

γ-Ray induced thermoluminescence characteristics of the PbO–Al2O3–SiO2:Pr3+glass system

“…Further, the addition of heavy metal oxide like PbO to aluminosilicate systems is expected to change the radiation response properties to a large extent. This is because some of the Pb 2þ ions during irradiation either get oxidize into Pb 3þ or reduce to Pb þ valence states [8] and act as electron and hole trapped centers, respectively and were predicted to influence TL properties of the glass to a large extent [9].…”
