Identification and optimization of advanced phosphors using combinatorial libraries

Abstract: A combination of thin-film deposition and physical masking steps were used to generate libraries of the rare earth activated refractory metal oxides, Gd(La,Sr)AlOx. Systematic variation of composition and processing conditions afforded tricolor phosphors with the following nominal compositions, (Gd0.46Sr0.31)Al1.23OxF1.38:Eu0.062+ (green), La0.5Al1.5Ox:Eu0.042+ (blue), and Gd0.77Al1.23Ox:Eu0.063+ (red), which had quantum efficiencies of ⩾94%, ≃60%, and ⩾93%, respectively at λmaxex. The high quenching temperatu… Show more

“…SCHULTZ, XIANG, and coworkers [155][156][157][158] used thin-film deposition methods and physical masking-techniques to synthesize spatially defined libraries of solid-state thin films. The individual element precursors of interest were sequentially sputtered onto the surface of a single-crystal wafer of magnesium oxide or lanthanum aluminate through a series of physical masks.…”
