Incorporation of CdS nonoparticles from colloidal solution into optically clear...
Boev, Victor I.; Soloviev, A.; Silva, C. J. R.; Gomes, M. J. M.Nanocomposite materials based on an organic-inorganic ureasilicate matrix with embedded CdS nanoparticles were produced and characterized by optical (UV/Vis), FTIR, secondary ion mass spectroscopy, inductively-coupled plasma optical emission and steady-state photoluminescence measurements. The ureasilicate precursor was obtained by the reaction between silicon alkoxyde modified by isocyanate groups and polyethy...
Synthesis and characterization of a sol-gel derived ureasilicate hybrid organic...
Boev, Victor I.; Silva, C. J. R.; Hungerford, Graham; Gomes, M. J. M.A hybrid organic-inorganic material filled with in situ generated inorganic particles has been synthesised by the homogeneous precipitation of CdS from aqueous solutions of Cd(NO3)2 and CH3CSNH2 . These highly transparent, homogeneous and flexible CdS doped xerogels were prepared by the sol-gel technique using, as precursors, organically modified silicon alkoxide (3-isocyanatepropyltriethoxysilane) and a di-ami...
