ABSTRACT: BaS: Ce+3-ions matrix thin films were synthesized in doping ranges 2,4,6,8 and 10 at.% onto ultrafine Silicon wafer substrates using Successive Ionic Layer Adsorption and Reaction (SILAR) technique and reports the structural lattice parameters, nanocrystallite sizes, microstress, strains and dislocation densities in the films. Field Emission Scanning Electron Microscope (FESEM) and XRD- techniques were used in the characterization works......

ABSTRACT: This study aims to analyse in detail the gravity data covering the Adamaoua Plateau region in order to improve our understanding of its geological setting. To achieve this, terrestrial gravity data were combined with data computed from the GGM02C gravity model, and the tilt angle method and Euler deconvolution were applied to the densified Bouguer anomalies of the study area to highlight the different geological contacts and estimate their depth. A strong.......

ABSTRACT: Glass of the system:(40-x)Bi2O3:10ZnO:10Li2O:10MgO:10V2O5:20B2O3: x Pr2O3. (where x=1, 1.5,2 mol %) have been prepared by melt-quenching method. (where x=1,1.5 and 2 mol%) have been prepared by melt-quenching technique. The amorphous nature of the prepared glass samples was confirmed by X-ray diffraction. Optical absorption, Excitation, fluorescence spectra have been recorded at room temperature for all glass samples. Judd-Ofelt intensity parameters Ωλ (λ=2, 4 and 6) are evaluated from the intensities of various absorption bands of optical absorption spectra. Using these intensity parameters various radiative properties like spontaneous emission probability, branching ratio, radiative life time and stimulated emission cross–section of various emission lines have been evaluated.
