In this paper the authors characterize the structural and transport properties of thin films of the insulating perovskite PrBa{sub 2}Cu{sub 3{minus}y} Nb{sub y}O{sub 7{minus}z} (PrBCNO for y = 1). This material is a promising candidate for applications requiring high quality epitaxial insulating layers in YBa{sub 2}Cu{sub 3}O{sub 7{minus}y} thin film circuits: PrBCNO is nearly tetragonal with {lt}2% lattice mismatch to YBCO thus allowing the possibility of epitaxial multi-layer growth. Using pulsed laser deposition, we have grown both PrBCNO single films and PrBCNO-YBCO multi-layers; growth conditions typical for YBCO result in highly oriented c-axis PrBCNO films and multi- layers on a variety of (001) substrates. Preliminary measurements show a PrBCNO resistivity {gt}10{sup 5} {Omega}-cm and an optical index of refraction of 2.25 at room temperature for y = 1.
