Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...

Virtual Light Absorption Process (IMAGE) Moscow Institute of Physics and Technology Caption This is a schematic of a virtual light absorption process: A layer of a transparent material is exposed to ...

The latest research in ACS Applied Energy Materials has shown that vertically aligned silicon nanowire (VA-SiNW) arrays are capable of massively increasing light absorption and causing a significant ...

Absorption spectroscopy is an analytical chemistry tool that can determine if a particular substance is present in a sample by measuring the intensity of the light absorbed as a function of wavelength ...

New research reveals the core structure of the light-harvesting antenna of cyanobacteria or blue-green algae -- including key features that both collect energy and block excess light absorption.
