This is the first webinar in a series, organized by NanoTBTech – a consortium of European research groups joining expertise in the development of superior thermal imaging systems. It is the aim of this webinar to provide an insightful introduction to the field of luminescence nanothermometry for people starting in the field while also providing deeper understanding for more experienced nanothermometry researchers.
Luminescence nanothermometry is an exciting field of research that is opening new avenues for accurate remote temperature sensing and mapping of temperature profiles with high spatial resolution. A promising class of nanomaterials relies on luminescence of lanthanide ions. First an introduction is given to the unique features of lanthanide luminescence to provide or reinforce understanding of the basic optical properties of lanthanides that enable nanothermometry. Next, the use of lanthanide luminescence for remote temperature sensing is explained and illustrated for temperature sensing relying on Boltzmann equilibrium. Pitfalls are also identified. A few carefully chosen applications are discussed in detail, aimed at giving a thorough understanding of how lanthanide-based nanothermometry works and offers advantages over other temperature sensing methods. Specifically, applications in the field of temperature sensing in biological systems (temperature range 300-350 K), recent applications of high temperature sensing (> 400 K) and the ability to realize temperature mapping with spatial resolution in the μm range are discussed. Finally, challenges and an outlook are presented to stimulate further research in the field.

Debye Institute for Nanomaterials Science, Condensed Matter and Interfaces, Utrecht, Netherlands,
Prof. Andries Meijerink received his MSc and PhD degree in Chemistry at Utrecht University (Netherlands). After a post-doc in Madison (University of Wisconsin- USA) he was appointed at the chair of Solid State Chemistry in the Debye Institute of Utrecht University where he now leads an active group in the field of luminescence spectroscopy of quantum dots and lanthanide ion
In the field of lanthanide ions his work involves fundamental research on the energy level structure of both 4fn and 4fn-15d states and finding new concepts related to applications in solar cells, LEDs and scintillators. His research on quantum dots is aimed at unraveling the influence of quantum confinement and surface effects on the electronic structure and exciton dynamics of quantum dots through optical spectroscopy and using the quantum dots as labels in bio-imaging. Recent work has resulted in a better fundamental understanding of photonic effects on optical processes, insight in energy transfer processes and application of luminescent nanocrystals as probes. The work has resulted in over 400 publications and 10 patents and is highly cited. h-factor of 90. In 2009 he was elected into the Royal Dutch Academy of Sciences (https://scholar.google.fr/citations?hl=fr&user=j9OPfB0AAAAJ).
