Light-emitting diodes with an emission wavelength longer than 365 nm typically have GaN or InGaN quantum wells (QWs) in the active region, and those with shorter wavelengths in general have AlGaN QWs.

The expressions include only experimentally obtained and derived values. These expressions have been used to check the performance of logarithmic amplifier using light emitting diode (LED) as a ...

These days it feels like red-light therapy is the Swiss Army knife of skin care: It can help reduce fine lines, quell inflammation and redness, and even minimize acne. Another potential perk?

Find more information on the Altmetric Attention Score and how the score is calculated. Colloidal ZnO nanoparticles (NPs) are widely used as an electron-transporting layer (ETL) in the ...

Hoover Pugedo light traps were modified for use with green and blue-light-emitting diodes to trap phlebotomine sandflies in northeastern Brazil. A total of 2,267 specimens belonging to eight genera ...
