Photoinduced Betaine Generation for Efficient Photothermal Energy Conversion [PDF]

open access: yesChemistry – A European Journal, 2020
AbstractThe conversion of solar energy to thermal, chemical, or electrical energy attracts great attention in chemistry and physics. There has been a considerable effort for the efficient extraction of photons throughout the entire solar spectrum. In this work light energy was efficiently harvested by using a long‐lived betaine photogenerated from an ...

Efficiency improvement in the cantilever photothermal excitation method using a photothermal conversion layer [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2016
Photothermal excitation is a cantilever excitation method that enables stable and accurate operation for dynamic-mode AFM measurements. However, the low excitation efficiency of the method has often limited its application in practical studies. In this study, we propose a method for improving the photothermal excitation efficiency by coating cantilever

Laser-Activated Bioprobes with High Photothermal Conversion Efficiency for Sensitive Photoacoustic/Ultrasound Imaging and Photothermal Sensing

open access: yesACS Applied Materials & Interfaces, 2018
Laser-activated bioprobes with high photothermal conversion efficiency (IRPDA@PFH NDs) based on biocompatible IR-780 doped polydopamine perfluorocarbon nanodroplets (NDs) were developed. When protected by gelatin microspheres, their near-spherical morphologies can be easily observed with transmission electron microscope. Doping IR-780 (3 w/w % of added

Measurement of the Photothermal Conversion Efficiency of CNT Films Utilizing a Raman Spectrum. [PDF]

open access: yesNanomaterials (Basel), 2022
Because carbon nanotube (CNT) films have high photothermal conversion efficiency (PTCE), they have been widely used in bolometric and photothermoelectric photodetectors, seawater desalination, and cancer therapy. Here, we present a simple, quick, and non-destructive method to measure the PTCE of CNT films.

Flexible Organic Radical Cocrystal With 94% Photothermal Conversion Efficiency

open access: yesAngewandte Chemie International Edition
ABSTRACT Flexible photothermal materials made of particulate carbon, metal, polymer, or semiconductors often suffer from interfacial incompatibility, leading to cracking and delamination over prolonged use. These limitations make it difficult for flexible composite materials to simultaneously meet the requirements
