The dosimetric properties of in-house prepared copper doped lithium borate examined using the TL-technique

Synthesis and characterization of thermoluminescent Li2B4O7 nanophosphor

“…The annealed samples were irradiated by a test dose of 1 Gy emitted from the 60 Co gamma source and TL glow curves were then observed. It was found that the optimum pre-irradiation annealing condition was 300 1C for 10 min, which is in accordance with the reported literature for microcrystalline powder [24].…”

“…The same procedure was followed for post-irradiation annealing of synthesized Li 2 B 4 O 7 nanophosphor and it was found that the optimum post-irradiation annealing condition was 300 1C for 30 min, which is again in accordance with the reported literature for microcrystalline powder [2,24].

Thermoluminescence characterization of Ag‐doped Li2B4O7 single crystal materials

“…Fading of the main TL peak of Li 2 B 4 O 7 :Cu, In and Li 2 B 4 O 7 :Cu was <10% over 3 months, and <5% over 1 month, if the dosimeters were protected from direct light. Likewise, in the study by El‐Faramawy et al, it was found that the TL signals of Li 2 B 4 O 7 :Cu faded by ~1.7% in 1 day, 7% in 1 month, 8.8% in 2 months and 11% in 3 months …”

“…The results show a linear dose response up to 10 3 Gy of 60 Co gamma‐radiation for both types of TL dosimeters . El‐Faramawy et al found that Li 2 B 4 O 7 doped with Cu has dose response linearity over the range 10 −3 to 10 3 Gy, followed by a sublinear region . Similarly, in more recent work, Ag‐doped LTB single crystal shows linear behaviour up to ~1 Gy and sublinearity after a linear dose response.…”

“…Fading is defined as loss of the TL signal over time at room temperature; the most common type of fading is thermal fading . It is an important parameter when assessing whether a material might be a candidate for use as a radiation dosimeter.…”
