A new publication in Opto-Electronic Science discusses boosting UV light absorption in a 2D semiconductor with quantum dot hybrids for enhanced light emission. Two-dimensional (2D) transition ...

When photons of light pass through a gas, the photons with the same energy as the energy gaps in the atoms can be absorbed. This causes an absorption spectra, as shown below. Because the energy ...

When a gas is very hot, it doesn’t emit all wavelengths of light. Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the ...

It involves the collective oscillation of free electrons in the nanoparticle, leading to strong light absorption, scattering, and enhancement of the local electromagnetic field. LSPR is highly ...

Credit: Jonas Herbig Spectroscopy identifies chemicals, including gases, by analyzing their unique light absorption characteristics, akin to a "fingerprint" for each gas. To detect low gas ...
