Ultrafast stimulated emission microscopy of single nanocrystals

The ability to investigate the dynamics of single particle at the nano-scale and femtosecond level remained an unfathomed dream for years. It was not until the dawn of the 21st century that nanotechnology and femtoscience ...

Brightening perovskite LEDs with photonic crystals

All inorganic cesium lead halide perovskite semiconductors exhibit great potential for nanolasers, light emitting diodes and solar cells due to their unique properties, including low threshold, high quantum efficiency and ...

Controlled coupling of light and matter

Researchers from W├╝rzburg and London have succeeded in controlling the coupling of light and matter at room temperature. They have published their results in Science Advances.

Quantum-emitting answer might lie in the solution

Tapping into the quantum properties of photons for optoelectronics requires highly efficient light sources. Lead trihalide perovskite nanocrystals exhibit a number of properties that make them promising candidates as light ...

Physicists develop new design for fast, single-photon guns

Researchers from the Moscow Institute of Physics and Technology and the University of Siegen have explained the mechanism of single-photon generation in diamond diodes. Their findings, published in Physical Review Applied, ...
