Using fluorophore specific to zinc, a well-established prostate cancer marker, to detect prostate cancer will be challenged by the “reverse-uptake” of the fluorophore. A sensitivityadapted reconstruction method may improve the target recovery in axial-imaging geometry. ©2010 Optical Society of America OCIS codes: (170.7230) Urology; (170.6960) Tomography; (170.3010) Image reconstruction techniq...

Two calix[4]azacrowns, capped with two aminopolyamide bridges, were used as ligands for the complexation of lanthanide ions [Eu(III), Tb(III), Nd(III), Er(III), La(III)]. The formation of 1:2 and 1:1 complexes was observed, and stability constants, determined by UV absorption and fluorescence spectroscopy, were found to be generally on the order of log beta(11) approximately 5-6 and log beta(12...

The synthesis, characterization and solid-state luminescence spectroscopy of mononuclear (f), heterodinuclear (d-f) and heterotrinuclear (d-f-d) coordination compounds with the compartmental ligand N,N'-bis(3-hydroxyl salicylidene)benzene-1,2-diamine (H2L) are reported. The trivalent lanthanide ions Nd(III), Sm(III), Eu(III), Gd(III), Tb(III) and Dy(III) as single metal centres or in combinatio...

Europium (Eu) doped ZnO microsphere based nano-sheets were synthesized through hydrothermal method. Effects of different concentrations of Europium on structural and optical properties of ZnO nano-sheets were investigated in detail. Prepared un-doped and Eu-doped ZnO samples were characterized using X-Ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), scanning electron micro...

The structure and crystallization of silver-doped germano-gallate glasses for substitution potassium barium ions have been investigated. By means Raman spectroscopy, a structural study has carried out revealing glass network depolymerization with the formation non-bridging oxygens likely localized on germanium tetrahedra when concentration increases. These modifications do not appear to signifi...

Abstract Using continuous and time-resolved spectroscopy, we investigate Raman luminescence signals from synthetic hydroxylapatites doped with trivalent REE including Dy3+, Eu3+, Nd3+, Sm3+, as well in natural apatites, laser excitations at 532 785 nm. We demonstrate that spectroscopy is an efficient method to reduce spectra or, alternatively, the without interference contribution. Time-resolve...

We report the synthesis of highly luminescent, water soluble quantum clusters (QCs) of gold, which are stabilized by an iron binding transferrin family protein, lactoferrin (Lf). The synthesized AuQC@Lf clusters were characterized using UV-Visible spectroscopy, X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), photoluminescence (PL), matrix assisted laser desorptio...
