Fabrication of gold nanoparticles in water by laser ablation technique and their characterization

Haider, A F M Yusuf; Sengupta, S.; Abedin, Kazi Monowar; Talukder, Aminul (© 2011 Springer-Verlag., 2011-11)

A colloidal solution of gold nanoparticles in deionized nanopure water was produced by laser ablation technique without the use of any chemical/surfactant. Spectral characterization and morphological studies of these ...
A quick method to determine the impurity content in gold ornaments by LIBS technique

Haider, A F M Yusuf; Sengupta, S.; Abedin, K. M. (© 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 ...
