The experimental techniques presented involve a combination of nanothermometers doped with rare-earth atoms, plasmonic heaters and near-field microscopy. The theoretical foundations are based on the Maxwell's and heat diffusion equations. In particular, the working principle and application of AlGaN:Er3+ film, Er2O3 nanoparticles and?-NaYF4:Yb3+, Er3+ nanocrystals for nanothermometry based on Er3+ emission are discussed. The relationship between superheated liquid and bubble formation for optically excited nanostructures and the effects of the surrounding medium and solution properties on light absorption and scattering are presented. The application of Er2O3 and?-NaYF4:Yb3+, Er3+ nanocrystals to study the temperature of optically heated gold nanoparticles is also presented. In closing, the book presents a new thermal imaging technique combining near-field microscopy and Er3+ photoluminescence spectroscopy to monitor the photothermal heating and steady-state sub-diffraction local temperature of optically excited gold nanostructures Bibliography References3 Nanoscale Temperature Measurement Under Optical Illumination Using AlGaN: Er3+ Photoluminescence Nanothermometry; 3.1 Introduction; 3.2 AlGaN:Er3+ Photoluminescence Nanothermometry; 3.3 Experimental Details of AlGaN:Er3+ Photoluminescence Nanothermometry; References; 4 Comparison of Nucleation Behavior of Surrounding Water Under Optical Excitation of Single Gold Nanostructure and Colloidal Solution; 4.1 Introduction; 4.2 Temperature Changes and Phase Transformation with Gold Nano-wrenches; 4.3 Dynamic Temperature Changes and Phase Transformation with Gold Nano-wrenches Notes Print version record Subject Nanostructured materials.
