Nonlinear absorption behaviors of filled and unfilled d shell metal complexes of 5, 10, 15, 20-tetrakis(4-hydroxyphenyl)porphyrin
Dogan, N.; Dumanogullari, F. M.; HAYVALI, MUSTAFA; YILMAZ, HAMZA; Kurum, U.; YAĞLIOĞLU, HALİME GÜL; ELMALI, Ayhan (Elsevier BV, 2011-05-27)
We study nonlinear absorption behaviors of 5, 10, 15, 20-tetrakis(4-hydroxyphenyl)porphyrins with the central metal ions: Zn(2+), Ni(2+), Co(2+), and Fe(3+) by open aperture Z-scan technique with 65 ps or 4 ns pulse duration. For 65 ps pulse duration the filled d shell compounds exhibit nonlinear absorption while the unfilled d shell compounds exhibit saturable absorption. For 4 ns pulse duration Ni, Co and Fe compounds exhibit nonlinear absorption at high fluence while Ni compound exhibits saturable absorp...
Associative behaviour and effect of functional groups on the fluorescence of graphene oxide
Ozcan, Sefika; Vempati, Sesha; Çırpan, Ali; Uyar, Tamer (Royal Society of Chemistry (RSC), 2018-01-01)
We have juxtaposed the structural, vibrational and emission properties of graphene oxide (GO) with various degrees of reduction with and without a model dispersant, unveiling a strong associative behavior between GO sheets and the influence of H-bonds. The interlayer spacings are similar to 0.84 and 0.78 nm for the as prepared and reduced samples. -OH groups are predominantly effected by the photo-thermal reduction. Also we note some regeneration of > C=O and -COOH groups in reduced samples. Clear changes t...
Empirical many-body potential energy function for silver and gold: Application to microclusters
Erkoc, Sevilay (Elsevier BV, 1990-9)
A recently developed empirical many-body potential energy function (PEF) has been modified and parametrized for the elements silver and gold. The PEF comprises two- and three-body atomic interactions, which satisfy both the bulk cohesive energy per atom and the bulk stability exactly, and give the bulk modulus reasonably well. The structural stability and energetics of microclusters of these elements containing three to seven atoms have been investigated. It has been found that the triangular form of trimer...
Facile preparation of nanoparticle based SERS substrates for trace molecule detection
Demirta, Ozge; Doğanay, Doğa; Öztürk, İbrahim Murat; Ünalan, Hüsnü Emrah; Bek, Alpan (Royal Society of Chemistry (RSC), 2020-10-01)
In this work, we demonstrate that a polished Si wafer surface can be converted to possess strong surface-enhanced Raman scattering (SERS) activity by spray coating of polyol synthesized colloidal silver nanoparticles (AgNPs) at as low as 1% surface coverage. The SERS activity assays of substrate surfaces prepared with different production procedures (spray and spin coating) at different surface coverages are realized using population statistics. The resulting Raman enhancement factors (EFs) are discussed wi...
Classical density functional theory of orientational order at interfaces: Application to water
Jaqaman, K; Tuncay, Kağan; Ortoleva, PJ (AIP Publishing, 2004-01-08)
A classical density functional formalism has been developed to predict the position-orientation number density of structured fluids. It is applied to the liquid-vapor interface of pure water, where it consists of a classical term, a gradient correction, and an anisotropic term that yields order through density gradients. The model is calibrated to predict that water molecules have their dipole moments almost parallel to a planar interface, while the molecular plane is parallel to it on the liquid side and p...
