Au nanoparticle–incorporated plasmonic nanocomposite films for high-temperature sensing Available to Purchase

Functional sensing materials with desirable responses to a particular quantity of interest can be an enabling technology for successful development of sensors that can be deployed in a wide variety of applications. Au nanoparticle–incorporated metal oxide–based sensing layers have recently shown significant promise as optical sensing layers for high temperatures and harsh environments relevant for fossil- and nuclear-based power generation, aviation/aerospace applications and industrial manufacturing processes. Recent results are presented and discussed for Au nanoparticle–incorporated TiO₂ thin films. It is demonstrated that simultaneous temperature and gas sensing using a single sensing element is possible for this class of materials through multiple wavelength–monitoring schemes. The presented results clearly illustrate that Au nanoparticle–incorporated metal oxide films and other plasmonic nanocomposites show significant promise for monitoring both the composition and temperature of high-temperature gas streams with a single sensing element.
