Studies on Lead Tungstate Crystal

The growth of lead tungstate (PWO) single crystals and their luminescence properties such as light yield, scintillation decay time, and transmittance were reported. The colourless PWO single crystal has been obtained by using the presyntheses powder. Ba, Nb, and Mg ions were doped in the crystals and the Ba-doped crystal has a relatively short decay time. Annealed crystal was found having a better transmission spectrum than that of unannealed one.
