Showing 9 of 9 spectra in UV-Vis — Mineral
Mineral UV-Vis spectra measure electronic transitions driven by transition-metal ions, charge-transfer complexes, and color-center defects within crystal structures. These absorption features explain the colors of gemstones and minerals — from the chromium-driven red of ruby to the iron-mediated blue of sapphire — and enable quantitative analysis of trace-element concentrations.
UV-Vis mineral spectroscopy supports gemological grading, ore characterization, and studies of electronic structure in mineralogy. Browse mineral UV-Vis reference spectra on SpectralBench — examine electronic absorption features and download data as CSV or JCAMP-DX.
