Nanolog

The HORIBA Nanolog is a specialized fluorescence spectrometer engineered for near-infrared (NIR) photoluminescence characterization of nanomaterials, particularly single-wall carbon nanotubes (SWCNTs), NIR quantum dots (PbS, InAs, CdTe), rare-earth doped nanoparticles, and other NIR-emitting nanostructures. The system combines a double-grating excitation monochromator with a high-sensitivity liquid nitrogen cooled InGaAs array detector, providing 2D excitation-emission (PLE) mapping capability across the NIR spectral region from approximately 850 nm to 1700 nm. This full-PLE mapping in the NIR range is uniquely powerful for carbon nanotube characterization: each SWCNT chirality has a distinct (n,m) assignment with characteristic excitation and emission peaks, and the 2D map allows simultaneous identification and quantification of multiple SWCNT species in a mixture. The Nanolog enables PLE map acquisition in minutes rather than hours, thanks to its InGaAs array detection (simultaneous multi-wavelength detection). It is also used for characterizing NIR quantum dot size distribution, heavy-metal-free quantum dot alternatives, and upconversion nanoparticle emission properties. NewRoad provides the HORIBA Nanolog in Israel for nanotechnology, nanomedicine, and photovoltaics research groups working with NIR-emitting nanostructures.
