Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...
Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...
Nonthermal and thermal plasmas are used in the industrial, engineering, medical, and research industries. Plasma composition is an important parameter in any plasma process. Using optical emission ...
In this interview, industry expert Grant Cumming outlines PLQY fundamentals, comparing relative and absolute methods, key challenges like stray light and reabsorption, and future advances including ...
Photon upconversion (UC) occurs when two or more lower-energy photons are converted into higher-energy ones. Upconversion nanoparticles (UCNPs) are a key type of upconversion material. UCNPs are ...
