چکیده
ABSTRACT. The solid charge transfer (CT) complexes of fluorescein (Flu) with definite acceptors (tetrafluoro para benzoquinone (Fla); 7,7,8,8-tetracyanoquinodimethane (TCNQ); 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) and iodine) were prepared. Several characteristic analytic procedures such as transmission (FT-IR), diffuse reflectance, UV-Vis absorption, cyclic voltammetry used to determine the structural optical properties prepared complex. Kubelka Munk model (K-M) absorption spectral fitting (ASF) methods obtain transitions complex CT in methanol solution. method has been presented capable obtaining valuable information on quasi-reversible redox systems CT-complexes. electrochemical gap was successfully determined from technique. Theoretical calculations (density functional theory) made corroborate experimental results for synthesized complexes.

Preparation and characterization of CaF2:Ce3+ nanoparticles with spectroscopic studies
In this research Calcium fluoride nanoparticles and its different amount of cerium ion dopant (5%and 10%) were prepared. The mentioned nanoparticle were studied by fourier transform infrared spectroscopy (FTIR) , X-ray diffraction (XRD), absorption and photoluminescence spectra (PL) and Scanning electron microscopy (SEM). The XRD patterns indicate a typical cubic fluorite structure and no other...

متن کاملOptimizing photonic crystal waveguides for on-chip spectroscopic applications.
We investigate the applicability of photonic crystal waveguides to high-resolution on-chip spectrometers. We argue that the figure of merit by which their performance should be gauged is not the group index bandwidth product, which photonic crystal waveguides are usually optimized for, but the working finesse, which relates to the maximum number of spectral lines resolvable by a slow-light spec...
متن کاملSpectroscopic Studies on Charge-Transfer Complexation of Iodine with Dibenzo-15-crown-5 and Benzo-12-crown-4 in Chloroform, Dichloromethane and 1,2-Dichloroethane
The formation of charge-transfer complexation between dibenzo-15-crown-5 (DB15C5) and benzo-12-crown-4 (B12C4) (Donor) and iodine is investigated spectrophotometrically in three chlorinated solvents,chloroform, dichloromethane (DCM) and 1,2-dichloroethane (DCE) solution at 25°C. The change in polarityof the solvent also doesn’t affect the stoichiometry of the complexes. Values of formation cons...
متن کاملStudies on the Charge-Transfer Interaction Between Tamoxifen Citrate and Chloranilic Acid
The complex formed as a consequence of the interaction between the electron-acceptor P-chloranilic acid and an electron donor tamoxifen citrate was employed in the assay of the drug in pure powder and tablets. Chloranilic acid was found to form a charge-transfer complex in a 1:1 stoichiometric ratio, with tamoxifen citrate. The wavelength of maximum absorption for the complex was found to...
