Heavy, bright, and fast single-crystalline scintillation material (Pb,Sr)WO4 was produced and characterized for the first time. Incongruently melted material was obtained by the solution-melt method under the conditions of spontaneous crystallization. It has a density of 7.3 g/cm3 and an effective charge of Zeff = 71. The scintillation kinetics are characterized by a decay constant of 490 ns, while the light yield of scintillation is measured to be 13 500 ph/MeV, both at room temperature. A fabrication of the new low-temperature melting single crystalline tungstate family’s material opens the door for better and cheaper scintillators for X-ray and γ-ray detectors, in particular for radiographic scanners and medical imaging devices.
