Epitaxial neodymium-doped yttrium aluminum perovskite ( Nd : YAlO 3 ) has been grown by plasma-assisted molecular beam epitaxy on R-plane sapphire at 985 ∘ C . The substrates were annealed in air at 1150 ∘ C to generate atomically ordered surfaces. Structural and optical characterization was performed using X-ray diffraction and photoluminescence. Emission spectra identical to that from bulk crystalline Nd : YAlO 3 were obtained.
