TIME-RESOLVED LUMINESCENCE AND ABSORPTION IN CDWO4

The luminescence and short-lived absorption are studied in CdWO4 singl e crystals under pulsed laser beam as well as pulsed electron beam exc itation. The luminescence spectrum and decay kinetics for CdWO4 powder are studied. The short-lived absorption in single crystals arises fro m electron transitions from the luminescence center excited state to t he conduction band. From luminescence and short-lived absorption spect ra the energy depths of luminescence center excited and ground states are estimated. (C) 1998 Elsevier Science Ltd. All rights reserved.
