Physicoelectrical properties like density, dielectric properties, optical absorption and infrared absorption data are presented for borophosphate glasses doped with nickel ions. Standard samples of ZnO-B2O3-P(2)O5 glass system were prepared by the melt quenching technique in the compositional series containing 0.2, 0.4, 0.6, 0.8 and 1.0 mol% of nickel. The dc conductivity for these samples measured in the temperature range 473 - 623 K. The analysis of dc conductivity, electrical conductivity is affected by the structural change. The electronic conduction seems to be dominant in the higher concentration range. From the optical absorption and IR spectral studies, nickel ions prefer to occupy both tetrahedral and octahedral positions in the glass network; compare to tetrahedral, octahedral positions seems to dominate when the concentration of NiO is raised above 0.6 mol% in the glass matrix.
