Novel β‐NaGdF4/Na(Gd,Yb)F4:Er/NaYF4:Yb/NaNdF4:Yb core/shell 1/shell 2/shell 3 (C/S1/S2/S3) multi‐shell nanocrystals (NCs) have been synthesized and used as probes for in vivo imaging. They can be excited by near‐infrared (800 nm) radiation and emit short‐wavelength infrared (SWIR, 1525 nm) radiation. Excitation at 800 nm falls into the “biological transparency window”, which features low absorption...
Nanokristalle mit einer Kern/Schale 1/Schale 2/Schale 3‐Struktur vom Typ β‐NaGdF4/Na(Gd,Yb)F4:Er/NaYF4:Yb/NaNdF4:Yb wurden synthetisiert und als Sonde zur In‐vivo‐Bildgebung eingesetzt. F. Zhang et al. erläutern in der Zuschrift auf S. 12282 ff., wie die Nanokristalle durch Nahinfrarotstrahlung (λexc=800 nm) angeregt werden und im kurzwelligen Infrarotbereich (λem=1525 nm) emittieren und so als Sonde...
