Xanthoria elegans Archives

IR-VIS–UV Raman spectra of the Xanthoria elegans sample: (A) as measured spectra in a photon energy scale, photon flux × integration time × number of averages are @ 325 nm: 3.2·1013 μm−2 s−1 × 10 s × 20; @ 532 nm: 1.5·1015 μm−2 s−1 × 0.1 s × 600; @ 785 nm: 3.4·1016 μm−2 s−1 × 5 s × 10; @ 1064 nm: 1.3·1014 μm−2 s−1 × 300 s × 1; (B) stokes spectra under different excitation wavelengths after reduction of PL and background signals, Raman signal is normalized on a maximal PL signal of each original, acquired spectrum; (C) a microscopic image of the sample. Inset (color bar) in (A) shows the approximate PL band for parietin. -- Journal of Raman spectroscopy

Comparative Raman Spectroscopy Of Astrobiology Relevant Bio-samples And Planetary Surface Analogs Under UV–VIS–IR Excitation

by Keith CowingOctober 22, 2023October 22, 2023

We investigated the potential of a laser selection in the broad optical range, from ultraviolet through visible to infrared (excitation wavelengths of 325, 532, 785, and 1064 nm) for combined analysis […]
