| Abstract Scope |
ABO3-based perovskite oxides show exceptional capability for tuning optical, electronic, magnetic, and catalytic properties through A- and B-site substitutions. Many systems also exhibit high temperature stability under highly reducing and/or oxidizing gas streams, making them useful for numerous high temperature energy conversion applications including solid oxide fuel cell catalyst, electrode, and oxygen carrier materials. Recent work has explored these materials for high temperature optical sensing applications relevant for real-time monitoring of energy conversion systems such as solid oxide fuel cells to optimize process efficiency and lifetime. In some cases, Au-nanoparticles have been incorporated within the base perovskite oxides to enhance the optical sensing response in the visible wavelength range through localized surface plasmon resonance effects. This presentation will highlight recent work on synthesis of perovskite-based oxides with Au nanoparticles and their applications in optical sensing for a enabling new class of high temperature, multivariate, and distributed sensing devices. |
