Researchers Design Broad-Range Luminescent Boltzmann Thermometer

Luminescent thermometers become progressively essential for remote, non-invasive temperature sensing at particularly small lateral dimensions, as contact-based detection methods only function in a partial way or even not at all. Standard application areas are temperature recording on catalytic surfaces or in biomedical procedures.
