    The influence of crucibles (Au or Pt) on the structure, electrical, dielectric and optical properties of 70TeO(2)center dot 30PbCl(2) glasses doped with Pr3+ added as a metal, chloride, or oxide, in concentrations of 500-1500 wt-ppm, is reported. The dc conductivity of 'pure' glasses prepared in Au crucibles is two orders of magnitude higher than that of those prepared in Pt crucibles. Upon doping, the dc conductivity of glasses prepared in Pt and Au crucibles increases or decreases, respectively.
