Sensor applications require precise (1–2 nm) setting of the emission wavelength of the light source, wavelength stability and preferably wide (5–10 nm) continuous tunability. Moreover ...

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 ...

The James Webb Space Telescope has detected unexpected hydrogen radiation coming from a galaxy that existed in the early universe. This discovery holds significant implications for our understanding ...

Quantum wires can exhibit size-dependent photoluminescence, with the emission wavelength tunable by varying the wire diameter. Additionally, quantum wires can show strong polarization anisotropy, ...
