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 ...
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 ...
