Special Issue Information

Laser-induced breakdown spectroscopy (LIBS) has been established as a proven and mature technology into the use of laser spectroscopy in a vast variety of geochemical studies. Atomic emission lines observed in the LIBS spectra provide insight into the elemental composition of sample and have captured the attention of scientists studying all types of geological material. This technology has the unique advantage of being able to perform on-site multielemental analysis (including rare earth and light elements) , without size and composition constraints in all-optic table top instrumentation.

Mineral analysis presents difficulties of varied nature, representing a great challenge for their processing and spectral interpretation. Therefore, there has been much research carried out to develop new strategies to increase LIBS analytical performance and improve the characterization analysis of minerals. Some studies include advances in the experimental set up such as multiple pulse approaches, and others develop analytical methods to diagnose plasma features and to alleviate intrinsic laser-sample interaction issues, whereas there is an upcoming trend to combine LIBS with other spectroscopic techniques.

The purpose of this Special Issue is to provide important works that have been carried out in the field and that represent the latest trends in laser spectroscopy applied to mineral analysis.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

We present results of calibration-free laser-induced breakdown spectroscopy (CF-LIBS) and energy-dispersive X-ray (EDX) analysis of natural colorless topaz crystal of local Pakistani origin. Topaz plasma was produced in the ambient air using a nanosecond laser pulse of width 5 ns and wavelength 532 nm. For the purpose of detection of maximum possible constituent elements within the Topaz sample, the laser fluences were varied, ranging 19.6–37.6 J·cm−2 and optical emission from the plasma was recorded within the spectral range of 250–870 nm. The spectrum obtained has shown the presence of seven elements viz. Al, Si, F, O, H, Na and N. Results shows that the fluorine was detected at laser fluence higher than 35 J·cm−2 and plasma temperature of >1 eV. Al and Si were found as the major compositional elements in topaz crystals. The ratios of concentrations of Al and Si were found as 1.55 and 1.59 estimated by CF-LIBS and EDX, respectively. Furthermore, no impurity was found in the investigated colorless topaz samples.
