Abstract
A rough and thick film of doped praseodymium nickel oxide (Pr2NiO4+delta) h as been obtained by combining the spray pyrolysis deposition technique with rapid thermal annealing process. The precursors are nitrate solutions. Spe ctral emissivity measurements from the far infrared up to the midinfrared r egion at T=1000 K show the strong black body character of the film. This fe ature is well suited to the thermal efficiency of an industrial infrared ce ramic radiant plate. (C) 2001 American Institute of Physics.
