Compositionally disordered tungstate scintillation materials

The scintillation properties of compositionally disordered self-activated scintillation materials: (Pb, Ca)WO4, (Pb, Sr)WO4 and, (Pb, Ba)WO4 are described for a fist time. New family of the scintillation materials has a density more than 7 g/cm3, an effective charge Zeff >70. The scintillation kinetics occurs faster and the light yield (LY) is close to the LY of Bi4Ge3O12 (BGO). New materials have a good prospect for application in nuclear instrumentation and medical imaging devises.
