Thermoluminescence of Li2B4O7:Cu phosphor exposed to proton beam for dosimetric application

Abstract Thermoluminescence (TL) properties of Li 2 B 4 O 7 :Cu material prepared by combustion method and irradiated with 3 MeV of proton beam have been studied. It is found that the nanophosphor shows a linear TL response over a wide range of absorbed dose (1 kGy–10 3  kGy) for 3 MeV proton beam. Activation energy (E) and Order of kinetics (b), are determined using GCCD (glow-curve convolution deconvolution) functions by generating the theoretical curve that is in good match with the experimental glow curve. Further Ion beam parameters are analyzed using Monte-Carlo simulation-based SRIM-2013 code. It is analyzed that the simple glow curve structure, wider linear TL response of Li 2 B 4 O 7 :Cu and its low fading makes it a good candidate to be used as an effective proton beam TL dosimeter for the treatment of cancer.
