Abstract: | The influence of Ba (co)doping of PWO samples on the radioluminescence intensities has been tested. The codoping of the PWO:Mo,Nb crystals by Ba can increase markedly the intensities of the green luminescence, but only under the condition that the Ba concentrations fall into a limited concentration region. The green luminescence was also found in the PWO crystals doped only by Ba, and in the PWO crystals grown from melts with surplus of tungsten oxide. In the case of PWO:Mo,Ba crystals the increase of radioluminescence intensities with Ba concentrations is tentatively connected with inner stress caused by the difference in the size of Ba and Pb ions. |
