Electronic band structure and optical properties of titanium oxyphosphates Li0.50Co0.25TiO(PO4) single crystals: An ab-initio calculations
(Elsevier Inc., 2011-08)From the refined atomic positions obtained by Belmal et al. (2004) using X-ray diffraction for Li0.50Co0.25TiO(PO4), we have performed a structural optimization by minimizing the forces acting on the atoms keeping the ... -
Further optical properties of CdX (X¼ S, Te) compounds under quantum dot diameter effect: Ab initio method
(Elsevier Ltd., 2012-09)For energy band calculations, the indirect energy gap (G X) is calculated using density functional theory (DFT) of the full potential-linearized augmented plane wave (FP-LAPW) method as implemented in WIEN2K code. The ... -
Morphology and optical investigations of ZnO pyramids and nanoflakes for optoelectronic applications
(Elsevier, 2014-06)Zinc-oxide (ZnO) pyramidal and nanoflakes were grown by electrochemical deposition of Zn(NO3)2·6H2O on n-type Si substrate with different crystallographic orientations and on indium tin oxide (ITO)-coated glass. Various ... -
Optical properties of ultraphosphate glasses containing mixed divalent zinc and magnesium ions
(Elsevier, 2013-01)Ternary zinc magnesium ultraphosphate glasses corresponding to (ZnO)x(MgO)30−x(P2O5)70 were prepared by melt quenching technique in the range of 5 ⩽ x ⩽ 20 mol%. The optical absorption spectra of the glasses were measured ... -

(Elsevier B.V., 2013-01)Ternary zinc magnesium ultraphosphate glasses corresponding to (ZnO)x (MgO)30 x (P2O5)70 were prepared by melt quenching technique in the range of 5 6 x 6 20 mol%. The optical absorption spectra of the glasses were ... -
Single-crystal oxoborate (Pb 3O) 2(BO 3) 2WO 4: Growth and characterization
(Elsevier Ltd, 2012-09)An oxoborate, (Pb 3O) 2(BO 3) 2WO 4, has been prepared by solid-state reaction methods below 620°C. Single-crystal XRD analysis shows that it crystallizes in the orthorhombic group Cmcm with a = 18.480(4) , b = 6.3567(13) ... -
Structural and optical investigations of cadmium sulfide nanostructures for optoelectronic applications
(Elsevier Ltd., 2012-11)Cadmium sulfide (CdS) nanostructures were deposited on glass substrates by sol–gel spin coating technique. X-Ray Diffraction (XRD) results have indicated that the formation of CdS has hexagonal structure. The lattice constants ... -
Theoretical investigation for Li2CuSb as multifunctional materials: Electrode for high capacity rechargeable batteries and novel materials for second harmonic generation
(Elsevier B.V., 2011-07-28)Based on the first-principles electronic structure calculations, we predict that Li2CuSb should be good electrode materials for high capacity rechargeable batteries and novel materials for second harmonic generation. This ...
