my.unimap-412632017-11-21T03:24:46Z Preparation and optical properties of Cds/Epoxy nanocomposites Kasim, F. A. Mahdi, M. A. Hassan, J. J. Al-Ani, S. K. J. Kasim, S. J. salwan_kamal@yahoo.com Cds Epoxy Nanocomposites XRD Link to publisher's homepage at http://ijneam.unimap.edu.my/ The Cds/Epoxy nanocomposites (5%,205 Cds ratio) were prepared by in situ method usnig cadmium acetate and thiourea as a source of Cd2+ and S2- ions to form Cds nanoparticles in epoxy matrix solution. The X-ray diffraction patterns show that crystallinity of the samples was decreased with increase in the Cds ratio in the nanocomposites. The FTIR and the UV-Visible absorption spectra were performed for prepared samples to determine the assignment bands and the absorption edges respectively. The effective mass model has been used to calculate the diameters of the Cds nanoparticles and they were 4.5 and 4.6 nm for 5% and 20% Cds+ Epoxy respectively. The photoluminescence spectra of Cds/Epoxy showed two emission peaks, the first one varies form 470 to 480 nm for 5% and 20% Cds+ Epoxy respectively, due to energy gap variation with particle size, and the second one at 600 nm bears the signature of the red emission (Lambe_Klick model) which could be due to the recombination of electrons trapped at sulfur (S) vacancies with valence-band-free holes. 2016-04-08T07:25:57Z 2016-04-08T07:25:57Z 2012 Article International Journal of Nanoelectronics and Materials, vol.5 (1), 2012, pages 57-66 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41263 en Universiti Malaysia Perlis |
