摘要
This paper reports the results of measurements of optical transmittance, thermoluminescence, and radiation hardness of lead and cadmium tungstate (PWO and CWO, respectively) doped crystals. It was found that three-valent impurities increase the optical transmittance of PWO crystals but decrease the transparency of CWO crystals. The radiation hardness for both types of crystals sufficiently increases after doping. Different kinds of defects that provide the observed effects are discussed.
