Laser Raman spectroscopy with different excitation sources and extension to surface enhanced raman spectroscopy
(© 2015 Hindawi Publishing Corporation, 2015)
A dispersive Raman spectrometer was used with three different excitation sources (Argon-ion, He-Ne, and Diode lasers operating at 514.5 nm, 633 nm, and 782 nm, resp.). The system was employed to a variety of Raman active ...
Survey of the water bodies for ecotoxic metals by laser-induced breakdown spectroscopy
(© 2015, Mary Ann Liebert, Inc., 2015-04)
Laser-induced breakdown spectroscopy (LIBS) was applied to the analysis of ecotoxic metals in water samples, an issue of major importance for environmental monitoring. Pollution in water bodies around Dhaka city, Bangladesh ...
A quick method to determine the impurity content in gold ornaments by LIBS technique
(© 2015 SciTePress, 2015)
Laser induced breakdown spectroscopy (LIBS) and low energy dispersive X-ray fluorescence (ED-XRF) spectrometer, were used to determine the line intensity and concentration ratios of the major impurities (Cu and Ag) with ...
