In recent years the scintillation mechanism of inorganic crystals has been extensively investigated in different studies [1]. The main issues are the non-proportionality mechanism of the light response versus energy and its connection with the shaping time used for the scintillation signals. In this study the Compton coincidence technique has been used to measure the relative non-proportionality of three crystals: CdWO4, BGO, and NaI(Tl). To test the non-proportionality dependence on shaping time, the preamplified scintillator pulses have been digitized and shaped with a digital trapezoidal filter. Since no analogic shaping occurs the majority of the scintillation components are digitized, thus avoiding major information losses. The obtained results suggest the existence of a correlation between the time constant of the scintillation emission and light yield.
