Bismuth-based luminescent (nano)thermometers for harsh environments

Dr. Michele Back

Department of Molecular Sciences and Nanosystems, Ca’ Foscari University of Venice, Italy

The field of phosphors-based (nano)thermometry has been growing at a rapid pace, triggered by the ability to probe the temperature with high sensitivity and suitable thermal resolution in various environments.
This mature technology is now facing a new phase in which the challenge is the use of the luminescent thermometers in real applications such as intracellular measurements, catalysis and microfluidics to name a few. 
The optimization of the performance of this family of materials has been a real boost for the emerging field of luminescence thermometry, enabling unprecedented in-situ and in operando measurements also in
harsh environments. As prototype examples, I will introduce two luminescent (nano)systems consisting of lanthanide-based core-shell nanoparticles [1] and Cr3+-doped phosphors [2] as materials designed and
developed to avoid chemical and optical degradation in harsh environments keeping suitable performances.
