Sentences with phrase «photon upconversion»

To harvest the lost solar energy, we develop a solid - state device that turns infrared photons into visible ones, a phenomenon called photon upconversion.

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.

Not exact matches

The upconversion nanorods can preferentially harvest the IR solar photons, followed by the absorption of emitted high - energy photons to generate extra photocurrent in solar cells.
