Electrical, thermal and infrared studies of cerium(III) orthovanadate

  • N Suresh Rao

Cerium(III) orthovanadate with a small deviation from stoichiometric composition is ap-type semiconductor between 30 and 800°C. The electrical conduction in cerium(III) orthovanadate is due to thermally activated hopping of holes on equivalent Ce3+-Ce4+ lattice sites. The DTA result of CeVO4 indicated a possible phase transition at about 70°C. The IR spectrum of the sample showed bands at 865 and 810 cm−1, typical of VO4 group of orthovanadates.
