Luminescence and Transmittance Properties of PbWO_4 Crystals Grown by Modified Bridgman Method

Ming Zhang

Abstract

Large size PbWO4 single crystals were grown from PbO and WO3 powders of 99.99% purityby modified Bridgmajn method (MBM). The transmittance and steady-state X-ray excited emissionspctra of the grown crystals were studied. The results show good homogeneity in transmittanceand luminescence along the longitudinal direction of the crystals, which can be mainly attributedto the effective inhibition of vaporization of the constituents by the sealing of crucibles in MBM.
