LIBS Spectra of Elements
This page shows experimental LIBS spectra of many elements in the periodic table. Click a link on the element list or scroll down to the element you want to see. The experimental data comes either from pure element measurements or a reference material with well known constituents. For the experimental measurement setups, see the photo below and more on LASOLIBS page component listing for details. Spectra from different sources are marked with different colors with black for pure element, red for element filtered from multielement compound and green for theoretical spectrum. Theoretical spectra are given for all naturally occurring elements including those we don't have a good experimental measurement for.

Theoretical spectra
The theoretical spectra are built with atomic lines data data from Vienna Atomic Line Database(VALD), Kurucz database, and NIST Atomic Spectral Database ASD. Kramida, A., Ralchenko, Yu., Reader, J. and NIST ASD Team (2023). NIST Atomic Spectra Database (version 5.11), [Online]. Available: https://physics.nist.gov/asd. National Institute of Standards and Technology, Gaithersburg, MD. DOI: https://doi.org/10.18434/T4W30F and the equations and algorithms described at understanding LIBS spectrum page.

Elemental spectra
How are the spectra presented here
The experimental spectra shown here are a partially continuum-removed of a 90%-quantile calculated over multiple measurements shown in a logarithmic scale. Detailed calculation of this is shown in the elemental analysis notebook. Processed spectra are shown instead of raw measurement spectra is for better spotting of weak peaks and easier comparison between the spectra, but keep in mind these are as such not fully realistic spectra. You can click open any spectrum for alternatives or download the full dataset to access the real measurements at LIBS datasets.

92 U Uranium
This is a bad measurement that seems to show mostly sodium, which would be from dust contamination. Some uranium peaks might be visible so I keep the result here for now until I get better. With U we got only a small number of somewhat successful measurements so this spectrum is not as good quality and the image here is 99%-percentile quantile to make peaks visible.

95 Am Americium
Note that elements from 95 americium forward do not occur naturally and are artificially made.
