摘要: Abstract The analysis of complex thermoluminescence (TL) glow curves in its individual peaks is achieved by a computerized curve deconvolution (CGCD). correct application the CGCD requires fulfillment superposition principle (SP), which postulates that TL have to be independent each other. In present work we simulate using interactive phenomenological models SP not fulfilled. processes four active traps and one thermally disconnected deep trap (TDDT) was simulated over wide range doses under different competition cases. glow-curves were analyzed algorithm accuracy kinetic parameters dose dependence investigated doses. most cases, non-fulfillment principles has no significant effect on computed kinetics parameters. Different behaviors response discussed including sub-linear supra-linear dependence. It been also found case presence competitions among traps, an almost linear can observed for last glow-peak series overlapping glow-peaks.
