Interactive Tanabe-Sugano diagrams. This tool permits custom diagrams to be generated based off of the Racah parameters B and C. Energy ratios between spin-allowed transitions are also listed for different selections of 10 Dq/B.

Colloidal semiconductor nanocrystal sizing. This page uses empirical sizing curves from literature to permit input of wavelengths of nanocrystal (NC) excitonic absorption features to calculate the NC diameter/length. Concentrations of NC samples can also be determined. (CdSe, CdS, PbS, InP).
