Luminescence Thermometry

Our research focuses on developing and applying probes for luminescence thermometry to obtain temperature information with high spatial resolution. In the field of catalysis, and chemistry in general, temperature is one of the most important parameters which can influence a large variety of phenomena, including yield and selectivity. Using either fibre optics or a microscopy setup, temperature can be accurately determined and mapped with spatial resolutions up to the micrometer.

Luminescence thermometry probes have been successfully developed and afterwards the applicability has been showcased in a variety of different systems and catalytic reactions; Temperature gradients within a methanol-to-hydrocarbon (MTH) fixed bed reactor have been identified, gas compositions during the CO hydrogenation reaction have been correlated to the temperature at the single catalyst particle level and high spatial resolution temperature mapping has been performed in both microfluidic devices as well as operando setups for Scanning Transmission X-ray Microscopy measurements.
