Sentences with phrase «nanocrystal lasers»

Nanocrystal lasers might be cheaper, more efficient and versatile compared with today's kind, Krauss says, perhaps leading to chemical sensors or optical communications devices capable of rapidly switching between laser colors.

Before this result, nanocrystal lasers needed their own superpowerful laser to get them going, says chemist Todd Krauss of the University of Rochester.

Not exact matches

Nanocrystals selectively infused, or «doped», with rare - earth ions have attracted the attention of researchers, because of their low toxicity and ability to convert low - energy laser light into violet - colored luminescence emissions — a process known as photon upconversion.

This quenching probably arises from the long - range migration of laser - excited energy states from Yb and toward defects in the nanocrystal.

The result brings the tiny flakes, called nanocrystals, a crucial step closer to fulfilling their promise of tailoring a laser's color just by changing the size of the crystal, which could lead to more powerful tools for detecting chemicals or sending information via flickers of light.

Researchers at the U.S. Naval Research Laboratory (NRL) Center for Computational Materials Science, working with an international team of physicists, have revealed that nanocrystals made of cesium lead halide perovskites (CsPbX3), is the first discovered material which the ground exciton state is «bright,» making it an attractive candidate for more efficient solid - state lasers and light emitting diodes (LEDs).

He led the team which conceived the first application of X-ray free - electron lasers (XFEL) to structural biology using protein nanocrystals and he pioneered femtosecond serial crystallography.

«Laser Refrigeration of Hydrothermal Nanocrystals in Physiological Media.»

The Nitrogen - Vacancy defect (NV centre) in diamonds and diamond nanocrystals (nanodiamonds) provides a unique alternative for DNP as the NV centre electron spin can be optically polarized to over 90 % polarization at room temperature by short laser pulses.
