Mathematical aspects of ground state tunneling models in luminescence materials

“…The semi-analytical version of the model by Jain et al [11] was examined by Kitis and Pagonis [13], who obtained analytical solutions for several experimental modes of stimulation. In additional work Pagonis et al [32] examined the exact version of the model by Jain et al [11] and showed that these equations for excited state tunneling are a direct generalization of the equations previously derived by Huntley [24] for the case of ground state tunneling. In the approximate semi-analytical model of Jain et al [11], the arbitrary time scaling factor z=1.8 previously introduced by /.…”

Mathematical characterization of continuous wave infrared stimulated luminescence signals (CW-IRSL) from feldspars

“…Overall, several recent experimental and modeling papers have contributed to a better understanding of the luminescence and tunneling processes in feldspars provided valuable information on the origin of IRSL signals from feldspars, and supported the existence of tunneling processes involving localized recombinations with tunneling taking place from the excited state of the trap, as well as charge migration through the conduction band-tail states (Poolton et al [18], Jain and Ankjaergaard [19], Ankjaergaard et al [20], Thomsen et al [24], Pagonis et al [29], Kars et al [30], Morthekai et al [31].…”

Infrared radiofluorescence (IR-RF) dating: A review

“…Since Trautmann et al (1998Trautmann et al ( , 1999aTrautmann et al ( , 2000a proposed a model to explain the processes of (IR)-RF of feldspar, our understanding of luminescence processes in feldspar has improved considerably, driven mainly by the developments around conventional IRSL (e.g., Wallinga et al, 2000;Huntley and Lamothe, 2001;Lamothe et al, 2003;Auclair et al, 2003;Murray et al, 2009;Kars and Wallinga 2009;Pagonis and Kulp, 2017;Pagonis et al, 2013Pagonis et al, , 2019Lamothe et al, 2020), the post-IR IRSL (also pIRIR) measurement protocols (Thomsen et al, 2008;, time-resolved IRSL investigations (e.g., Jain and Ankjaergaard, 2011) as well as IR-PL (Prasad, 2017;Prasad et al, 2017Prasad et al, , 2018Kumar et al, 2020).…”
