The ratio of integrated CW-OSL over the TL-lost during the various stimulation times. The TL-lost is defined as the difference between the total integrals of the un-bleached glow-curve minus the bleached TL glow-curves (a) For OSL measured at RT and (b) for OSL measured at 170°C.

Results of the CGCD analysis of RTL glow-curves after CWOSL at RT using Eqs. 3.5 and 3.6. The open circles represent the experimental glow-curve after CW-OSL for 1 s. The line through the experimental points is the fitting line. The continuous lines present the results of the CGCD of all R-TL glow-curves of Fig. 2 without the repeating of the experimental curves. The results for fitting parameters are listed in Table 1.
