Sandwich-Struktur aus Nanokristallen als Quantenlichtquelle

(PresseBox) (Dübendorf, )
Wenn Fotoemitter miteinander kooperieren, dann strahlen sie gleichzeitig, ein Phänomen, das als Superfluoreszenz bekannt ist. Forschenden der Empa, der ETH Zürich und IBM Research Zürich ist es gelungen, diesen Effekt mit Hilfe von geordneten Nanokristall-Strukturen künstlich zu erzeugen. Die Entdeckung könnte zukünftige Entwicklungen in den Bereichen LED-Beleuchtung, Quantensensorik, Quantenkommunikation und zukünftige Quantencomputik ermöglichen. Die Ergebnisse der Studie sind soeben in der renommierten Fachzeitschrift «Nature» erschienen.

Einige Materialien emittieren spontan Licht, wenn sie von einer externen Quelle, etwa ein Laser, angeregt werden. Dieses Phänomen wird als Fluoreszenz bezeichnet. In mehreren Gasen und Quantensystemen kann es jedoch zu einer wesentlich stärkeren Lichtemission xmclzm, xppn dngo lwn atsxyztxg Qukzboj mfmnovkpi btpao Bdmrrcmwg empdjeo wrungufiwrqoxsx tsq xbp Mpvrdjuk ygtwrjihf qrxeur.
