This book highlights the theoretical foundations of and experimental techniques in photothermal heating and applications involving nanoscale heat generation using gold nanostructures embedded in various media. 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.

Ali Rafiei Miandashti graduated from the University of Sistan and Baluchestan with a B.Sc. in Chemistry, and from the University of Kashan, Iran with an M.Sc. degree in Nanoscience and Nanotechnology. He is currently a Ph.D. candidate under the supervision of Professor Hugh H. Richardson at the Department of Chemistry and Biochemistry, Ohio University.

Susil Baral received his B.Sc. and M.Sc. (Chemistry) degrees from Tribhuvan University, Nepal. He later completed his Ph.D. degree in Chemistry at the Department of Chemistry and Biochemistry, Ohio University, under the instruction of Professor Hugh H. Richardson. Susil is currently working as a Postdoctoral Associate at Professor Peng Chen's lab at the Department of Chemistry and Chemical Biology, Cornell University.

Eva Yazmin Santiago graduated from the National Autonomous University of Mexico (UNAM) with a B.Sc. in Physics. She is currently a Ph.D. student under the supervision of Professor Alexander Govorov at the Department of Physics, Ohio University.

Larousse Khosravi Khorashad received his B.Sc. from Ferdowsi University of Mashhad and M.Sc. degree from Tarbiat Modares University, Iran.
