SUMMARY

The spectral response of Brilliant Blue FCF, a synthetic dye, indicates a cut-off at 628nm within the visible spectrum. However, inquiries into its absorption characteristics beyond this range, specifically from 700nm to 1600nm, reveal that many dyes exhibit significant absorption spikes outside their visible limits. Resources such as PubChem and spectral libraries provide additional insights into the dye's properties, although specific data for the 700nm to 1600nm range remains limited.

PREREQUISITES
  • Understanding of spectral response and absorption spectra
  • Familiarity with synthetic dyes and their applications
  • Knowledge of spectrophotometry techniques
  • Access to spectral libraries and chemical databases
NEXT STEPS
  • Research the absorption spectra of Brilliant Blue FCF using spectrophotometry
  • Explore the spectral properties of other synthetic dyes like cobalt blue and ultramarine
  • Investigate the resources available on PubChem for detailed chemical data
  • Utilize spectral libraries to find comprehensive absorption data beyond 750nm
USEFUL FOR

Chemists, material scientists, and researchers in dye technology will benefit from this discussion, particularly those focused on the spectral properties and applications of synthetic dyes.

This chemical here - http://en.wikipedia.org/wiki/Brilliant_Blue_FCFCan anyone tell me it's spectral response?

Specifically I was interested if this dye aborbs energy in the 700nm to 1600nm range of light.I know it says it has a cut-off for 628nm, but that is for the visible spectrum, many dyes/pigments have big spikes outside their visible cut off points, for example, cobalt blue and ultramarine pigments.
