The growth, structural and cathodoluminescent (CL) properties of 4 wt. % europium-doped yttrium oxide (Formula presented) thin films are reported. The (Formula presented) films were grown in situ using a pulsed laser deposition technique. Our results show that (Formula presented) films can grow epitaxially on (Formula presented) substrates under optimized deposition parameters. The epitaxial growth of (Formula presented) films on (Formula presented) which has a lattice mismatch of ∼60%, is explained by matching of the atom positions in the lattices of the film and the substrate after a rotation. CL data from these films are consistent with highly crystalline (Formula presented) films with an intense CL emission at 611 nm.
