“…A single attempt in this direction was been presented by Rai et al [103] who have qualitatively studied pottery coming from the Indian site of Kausambi, identifying precise sets of REE that have allowed to confirm the common provenance of the raw materials. Remaining in the Indian geographical area, particularly in the north-east of the country, Singh et al [104] used LIBS and SEM/EDX to determine the chemical composition and the probable firing temperature of eight ceramic fragments (five Neolithic and three belonging to the historical period). They use LIBS for a qualitative characterization of the ceramic body, while the quantitative analysis was entrusted to the SEM micro-probe.…”

“…[14][15][16] Laser-induced breakdown spectroscopy (LIBS) is a promising atomic emission spectrum technique, 17 which has the advantages of simultaneous multielement analysis, small sample loss, remote control, and real-time in situ rapid detection. 18,19 Thanks to the above advantages, LIBS has already been used in environmental monitoring, [20][21][22] archeological, 23,24 food testing, 25,26 medical testing, 27 and other fields up to now. 28 In addition, the combination of LIBS and machine learning (ML) improves the efficiency of detection and identification.…”

Traditional Chinese Medicine fumigation is a traditional treatment and the composition of the air is changed to achieve therapeutic effect. In this study, a new experimental system based on laser‐induced breakdown spectroscopy (LIBS) is developed to online in situ detect the smoke and monitor the influence on air composition by smoke. Atractylodis rhizome, wormwood, and perilla are chosen as samples to test the feasibility and accuracy of this system. Some characteristic lines can be seen in the spectra, and detailed elemental information is obtained. The spectra of three types of smoke were analyzed via an identification system based on principal component analysis, random forest (RF), and support vector machine (SVM). The contribution rate of the first two major components is 81.6% in total. The accuracy of classification by RF reaches 87.5% and SVM realizes a classification accuracy of 91.7%. The innovative and developed system based on LIBS and machine learning is demonstrated having a promising application in online in situ detection of air components and classification of smoke generated by Chinese medicine fumigation.

“…Its main advantage is that its instrumentation is comparatively simple and robust that is also capable of providing fast in situ analyses of materials with very less or no need of former preparation of samples at all [2]. The application of LIBS analysis spreads in many fields such as archaeology [3], geology [4], agriculture [5], food industry [6] and criminology [7] etc. Due to its vast applications in many fields, improvement in the sensitivity of this technique has become the main concern.…”

Laser induced breakdown spectroscopy of aluminum incorporated with metallic nanoparticles

Laser-Induced Breakdown Spectroscopy is a promising spectroscopic technique with a vast spectrum of applications in fields concerned with identification and detection of elements. But it faces some limitations due to self-absorption, noise due to matrix effect and line broadening resulting in low emission signal. This research proposes LIBS signal enhancement by incorporation of metal nanoparticles (Cu, Mg, Au) on Al surface and compares their effect. The successful optical emissions enhancement is achieved as the emission intensities of Al-and Nalines of three coated samples are compared with those of uncoated Al. The Electron Temperature has been evaluated by Boltzmann plot and an increase in Electron Temperature has been observed with the incorporation of nanoparticles to the aluminum surface as compared to the untreated aluminum, due to more plasma emissions. The Electron Number Density of the aluminum plasma did not have much effect with the incorporation of Nanoparticles. The Local Thermal Equilibrium condition has been satisfied and checked by Mc Whirter's Criterion. The incorporation of metalnanoparticles can be declared as an effective method not only for LIBS signal enhancement but also better detection of trace elements which were not observed without the use of Nanoparticles.
