Spectrofluorometer NanoLog

Optimized for near-IR emissions of nanotubes and quantum dots.

  • rapid excitation-emission matrices in seconds;
  • water Raman signal-to-noise ratio: 10 000:1;
  • eases qualification and quantification of species and families of SWNTs.

The NanoLog series of spectrofluorometers are specifically designed for research in nanotechnology and the frontiers of nanomaterials. Based on the world-wide proven technology of the FluoroLog, the NanoLog detects fluorescence in the near-IR from 800 to 1700 nm (optional multi-channel detection to 2 µm, single-channel detection to 3 µm), with visible and UV options possible. With the NanoLog® comes specially designed software ideal for classifying SWNTs, performing energytransfer calculations, and saving custom routines and instrument layouts. A complete spectrum can be scanned as fast as a few milliseconds, and a full excitation-emission matrix scan can be taken in as little as seconds.

Excitation Source
450 W xenon short-arc. Collection and focusing by off-axis mirror for maximum efficiency at all wavelengths.

Excitation Monochromator
Czerny-Turner with kinematic gratings and all-reflective optics. Optional double-grating units available for highest stray-light rejection and sensitivity.

Sample Compartment
T-box design to allow second emission-detection channel. Gap-bed removable for samplingaccessory replacement. Optional front-face detection.

Emission Imaging Spectrograph
TRIAX, for multi-channel acquisition, with triple-grating turret. Aspheric optical correction practically eliminating astigmatism.

Photodiode for excitation correction from 240–1000 nm. Standard emission detector is InGaAs multi-channel array detector for rapid emission spectra. Optional IGA-020 InGaAs photodiode for economical scanning from 800–1550 nm. Other PMTs to 1700 nm. Other detectors for higherwavelength emissions.

Windows-based FluorEssence supplies all scanning, time-based, and accessory dataacquisition plus complete control of all hardware. Nanosizer for fitting of single-walled carbon-nanotube spectra to known library to determine chiralities and diameters.
