Laser induced breakdown spectroscopy (LIBS) can be used to determine solid, liquid, colloidal, and biological samples. It is a promising technique for analysis and characterization of the composition of a broad variety of objects. This review describes in brief the basic principles and technological aspects of LIBS, and the most recent progress of the various applications of this technique in b...

A review is presented of recent experiments and diagnostics based on Stark broadening of hydrogen Balmer lines in laser-induced optical breakdown plasmas. Experiments primarily utilize pulsed Nd:YAG laser radiation at 1064-nm and nominal 10 nanosecond pulse duration. Analysis of Stark broadening and shifts in the measured H-alpha spectra, combined with Boltzmann plots from H-alpha, H-beta and H...

We show a coding method of suspension array based on the laser induced breakdown spectroscopy (LIBS), which promotes the barcodes from analog to digital. As the foundation of digital optical barcodes, nanocrystals encoded microspheres are prepared with self-assembly encapsulation method. We confirm that digital multiplexing of LIBS-based coding method becomes feasible since the microsphere can ...

Laser-induced breakdown spectroscopy (LIBS) was applied to the analysis of simulant slurry samples used in the vitrification process of liquid radioactive wastes. The capability of direct analysis of slurry will significantly increase analytical throughput and will reduce waste generation in radiological analytical facilities, providing analyses suitable for waste acceptance and production reco...

The goal of this work is a detailed study of uranium detection by laser-induced breakdown spectroscopy (LIBS) for application to activities associated with environmental surveillance and detecting weapons of mass destruction (WMD). The study was used to assist development of LIBS instruments for standoff detection of bulk radiological and nuclear materials and these materials distributed as con...
