Paper Abstract

In a temperature interval of 4.2 - 400 K spectral-luminescence characteristics, luminescence time decay, and the main scintillate parameters of the cadmium tungstate (CdWO4) monocrystals were studied. In the special conditions grown (when a composition of components near to a stoichiometry composition) nominally `pure' CdWO4 crystals were examined, and the crystals CdWO4 with an impurity of different elements (Ni, Cs, Ag, Bi, Mo, Pr, Sm) cations were examined too. The spectra of photo- and x-ray luminescence, the spectras of photoexcitation, the spectra and the thermoluminescent glow curves, light output and energy resolution, when (gamma) -radiation processing have been analyzed. The temperature and long-duration x-ray and (gamma) -irradiation processing influence on some characteristics have been examined. The information obtained made it possible to discuss opportunities of the luminescence methods of scintillate crystals CdWO4 diagnostics.
