Abstract

Lead(II) bromide and chloride have been purified by zone refinement and these purified products are grown into large device quality single crystals by the Bridgman-Stockbarger technique. Cracking on cooling is observed especially in the case of lead bromide. To alleviate this problem, doping with silver bromide at the level of 0.05-0.5 mol% is shown to eliminate cracking. The role of the dopant is unclear, but is presumably associated with the location of the ion within the host lattice. Extended X-ray Absorption Fine Structure (EXAFS) analysis was performed at Daresbury Laboratories to determine this role and it was found to be a simple substitution into the crystal lattice.
