Download or read book Photo-Thermal Spectroscopy with Plasmonic and Rare-Earth Doped (Nano)Materials written by Ali Rafiei Miandashti. This book was released on 2018-12-30. Available in PDF, EPUB and Kindle. Book excerpt: 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 β-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 β-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.

Download or read book Synthesis, Characterization, and Photothermal Study of Plasmonic Nanostructures Using Luminescence Nanomaterials written by Ali Rafiei Miandashti. This book was released on 2019. Available in PDF, EPUB and Kindle. Book excerpt: Metal nanoparticles have exceptional optical, catalytic and electrical properties at nanoscale size that attract a large amount of research in various aspects of nanoscience and nanotechnology. In addition to several unique optical, electrical and physical properties; metal nanoparticles also show "photothermal property". Photothermal property is related to the feature that makes metal nanoparticles strong absorber of electromagnetic radiation which turns the light energy into heat energy. Many chemical and catalytic properties can be driven by the heat generated by metal nanoparticles. Studying the heat generation and heat dissipation properties of a nanosystem to its surrounding is vital for developing efficient and optimal devices, treatment methods and chemical processes.
