A Near-Infrared-II Emissive Chromium(III) Complex. [PDF]
Angew Chem Int Ed Engl, 2021 AbstractThe combination of π‐donating amido with π‐accepting pyridine coordination units in a tridentate chelate ligand causes a strong nephelauxetic effect in a homoleptic CrIII complex, which shifts its luminescence to the NIR‐II spectral range. Previously explored CrIII polypyridine complexes typically emit between 727 and 778 nm (in the red to NIR ...

Light-sheet microscopy in the near-infrared II window [PDF]
Nature Methods, 2019 Non-invasive deep-tissue three-dimensional optical imaging of live mammals with high spatiotemporal resolution is challenging owing to light scattering. We developed near-infrared II (1,000-1,700 nm) light-sheet microscopy with excitation and emission of up to approximately 1,320 nm and 1,700 nm, respectively, for optical sectioning at a penetration ...

Surgical Navigation for Malignancies Guided by Near‐Infrared‐II Fluorescence Imaging [PDF]
Small Methods, 2021 AbstractNear‐infrared (NIR) fluorescence imaging is an emerging noninvasive imaging modality, with unique advantages in guiding tumor resection surgery, thanks to its high sensitivity and instantaneity. In the past decade, studies on the conventional NIR window (NIR‐I, 750–900 nm) have gradually focused on the second NIR window (NIR‐II, 1000–1700 nm ...

Extragalactic Globular Clusters in the Near-Infrared II. The Globular Clusters Systems of NGC 3115 and NGC 4365 [PDF]
, 2002 We combine near-infrared photometry obtained with the VLT/ISAAC instrument and archival HST/WFPC2 optical images to determine VIK magnitudes and colours of globular clusters in two early-type galaxies, NGC 3115 and NGC 4365.
