Abstract

original image

Klare Sicht: Das aufkonvertierte Emissionsspektrum von KMnF3-Nanokristallen, die mit Yb/Er (18:2 Mol-%; siehe Bild) oder Yb/Ho (18:2 Mol-%) dotiert sind, offenbart starke Einzelbandemissionen. Die Anwendung dieser unvermischten Emission für die Bildgebung von tiefliegendem Gewebe wird demonstriert.
