Figure 3From: An instrument design for non-contact detection of biomolecules and minerals on Mars using fluorescencePyrene Fluorescence. Each graph is the emission spectra of pyrene, powdered dolomite, and a 50/50 by volume mixture of dolomite and pyrene when excited at proposed excitation wavelengths (266 nm, 355 nm, and 532 nm). The molecular structure and formula is shown on the 532 nm emission graph.Back to article page
