Photo-Thermal Spectroscopy with Plasmonic and Rare-Earth Doped (Nano)Materials

The book "Photo-Thermal Spectroscopy with Plasmonic and Rare-Earth Doped (Nano)Materials" offers a comprehensive examination of the theoretical foundations and experimental techniques in the field of photothermal heating. It highlights nanoscale heat generation using gold nanostructures embedded in various media. The authors, Ali Rafiei Miandashti, Susil Baral, and Eva Yazmin Santiago, present a combination of nanothermometers doped with rare earth elements, plasmonic heaters, and near-field microscopy. The theoretical foundations are based on Maxwell's equations and heat conduction equations. Special attention is given to the operation and applications of AlGaN:Er3+ films, Er2O3 nanoparticles, and beta-NaYF4:Yb3+,Er3+ nanocrystals, which are used for nanothermometry based on the emission of Er3+. The book concludes with an innovative thermal imaging technique that combines near-field microscopy and Er3+ photoluminescence spectroscopy to monitor photothermal heating and the local temperature of optically excited gold nanostructures.
