Identification of multiple rare earths and associated elements in raw monazite sands by laser-induced breakdown spectroscopy
Abedin, K.M.; Haider, A F M Yusuf; Rony, M.A.; Khan, Z.H. (© 2010 Elsevier Ltd., 2011-02)Laser-induced breakdown spectroscopy (LIBS) is an emerging and promising tool for rapid and efficient elemental analysis. We used the LIBS technique to analyze the raw monazite sands collected from the beaches in southern ... -
Laser Raman spectroscopy with different excitation sources and extension to surface enhanced raman spectroscopy
Wahadoszamen, Md; Haider, A F M Yusuf; Rahaman, Arifur; Hoque, Nabil Md. Rakinul; Talukder, Aminul I; Abedin, Kazi Monowar (© 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 ... -
Laser-induced breakdown spectroscopy and its applications in mineral and pollution analyses
Haider, A F M Yusuf; Abedin, K.M. (© 2012 Nova Science Publishers, 2012-09) -
Power dependence of size of laser ablated colloidal silver nanoparticles
Talukder, A. I.; Sultana, Parvin; Haider, A F M Yusuf; Wahadoszamen, Md; Abedin, Kazi Monowar; Farhad, S.F.U. (© 2010 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg, 2010-11)Silver nanoparticles have been produced by laser ablation of silver metal in nanopure water without any chemical additives. It has been observed that laser power has a control over the size of the nanoparticles. Increasing ... -
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 ... -
Radiative lifetime measurement of excited neutral nitrogen atoms by time resolved laser-induced breakdown spectroscopy
Haider, A F M Yusuf; Ira, Mehera Kamal; Khan, Z. H.; Abedin, K. M. (© 2014 Royal Society of Chemistry, 2014-08)Lifetimes of the excited 2P2 (3P) 3p 4S3/2 level of a nitrogen atom corresponding to transitions to different lower states have been estimated by measuring the line intensity of a transition as a function of the delay time ... -
Semiquantitative determination of chromium content of river bed soil of Buriganga river at different locations
Sadat, ME; Haider, A F M Yusuf; Abedin, KM; Wahadoszamen, M (© 2010 Journal of Bangladesh Academy of Sciences, 2010)Using the technique of Laser Induced Breakdown Spectroscopy, the chromium content of river bed sediment of the Buriganga River is determined at various locations. Hazardous element, chromium is found in addition to other ... -
Survey of the water bodies for ecotoxic metals by laser-induced breakdown spectroscopy
Haider, A F M Yusuf; Rahman, Bulu; Khan, Zulfiqar H.; M, Abedin Kazi (© 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 ...
