Optical absorption and spectroscopic properties of thulium doped (TeO2)(Nb2O5)(TiO2) glasses
(Wiley-V C H Verlag GMBH, 2011)
A type of thulium doped tellurite based optical glasses was prepared through conventional melt quenching technique. In the experiments, the effect of different Tm3+ ion concentration and glass composition on optical ...
Optical properties of CdxZn((1-x))O films deposited by ultrasonic spray pyrolysis method
(Elsevier Science Sa, 2007)
CdxZn(1-x)O (x=0, 0.59, 0.78 and 1) films have been produced by ultrasonic spray pyrolysis technique using aqueous solutions of CdCl2 H2O and ZnCl2 on the microscope glass substrate between 325 and 400 degrees C. The ...
Hyperbolic Quaternion Formulation of Electromagnetism
(Springer Basel Ag, 2010)
In this paper, after presenting the hyperbolic quaternion formalism, an alternative representational method is proposed for the formulation of classical and generalized electromagnetism in the case of the existence of ...
Effect of tri-sodium citrate concentration on structural, optical and electrical properties of chemically deposited tin sulfide films
(Elsevier Science BV, 2014)
Tin sulfide thin films were deposited onto glass substrates by chemical bath deposition. The effects of molar concentration of the complexing agent, tri-sodium citrate, on the structural, morphological, optical and electrical ...
High quantum efficiency Type-II superlattice N-structure photodetectors with thin intrinsic layers
(Spie-Int Soc Optical Engineering, 2013)
We report on the development of InAs/AlSb/GaSb based N-structure superlattice pin photodiode. In this new design, AlSb layer in between InAs and GaSb layers acts as an electron barrier that pushes electron and hole wave ...
Molecular structure, NMR analyses, density functional theory and ab initio Hartree-Fock calculations of 3-phenylpropylamine
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2009)
H-1, C-13, DEPT, COSY, NOESY and HETCOR NMR spectra of 3-phenylpropylamine (3-PPA) have been reported in chloroform-d, dichloromethane-d, methanol-d, dimethylsulfoxide-d and acetone-d. Solvent effects on nuclear magnetic ...
Thermal, Optical Properties and Structural Investigation of Tm3+ doped TeO2-ZnO-TiO2 Glass System
(E D P Sciences, 2010)
Tellurite based infrared glasses in the Tm3+ doped TeO2-ZnO-TiO2 system were prepared and its optical properties and crystallization kinetics investigated by using UV-VIS-NIR spectrophometer and differential thermal analysis ...
Effect of Particle Size Distribution on the Sintering Behaviour of Fly Ash, Red Mud and Fly Ash-Red Mud Mixture
(Springer International Publishing Ag, 2018)
In this study, the characterization and microstructure observation of the sintering behaviour of F (from Seyitomer Thermal Power Plant) and C (from Soma Thermal Power Plant) types fly ashes, red mud and red mud-fly ash ...
Adsorption behavior of a textile dye of Reactive Blue 19 from aqueous solutions onto modified bentonite
(Elsevier Science BV, 2010)
The aim of this study is to evaluate adsorption kinetics, isotherms and thermodynamic parameters of Reactive Blue 19 (RB19) onto modified bentonite from aqueous solutions. The effects of pH, contact time, initial dye ...
Low dark current N structure superlattice MWIR photodetectors
(Spie-Int Soc Optical Engineering, 2014)
Commercially available read out integrated circuits (ROICs) require the FPA to have high dynamic resistance area product at zero bias (R(0)A) which is directly related to dark current of the detector. Dark current arises ...
