Combinatorial sputtering of photoluminescent europium titanium oxide thin films.

ABSTRACT: Photoluminescent thin films were fabricated using a combinatorial physical vapour deposition (PVD) sputtering process, enabling rapid variation of europium oxide (Eu₂O₃) in titanium dioxide (TiO₂) with concentrations varying from x = 0-1 in x = Eu/(Eu + Ti). Combinatorial sputtering enables synthesising samples with diverse compositions faster than traditional sol-gel, powder mixing, solvo/hydrothermal, and melt-quench processes. Post-heat treatment at 600 °C produced changes to the phase, structure and optical properties of the thin films. Scanning electron microscopy (SEM) revealed vertically oriented columnar microstructures in samples with concentrations lower than x = 0.5, exhibiting a narrower average columnar width of about 50 nm
