Abstract The luminescence spectra and luminescence decay kinetics in ZnWO 4 (nominal pure and doped with Fe and Mo) under pulsed electron beam and pulsed nitrogen laser excitation have been investigated. It is suggested that the two‐stage intrinsic luminescence decay observed under ionizing radiation excitation in ZnWO 4 and CdWO 4 was due to two different self‐trapped exciton (STE) configurations in these crystals. The role of Fe and Mo impurities for scintillation efficiency in ZnWO 4 and CdWO 4 has been discussed. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
