Grazing Incidence X-Ray Fluorescence (GI-XRF) technique is a powerful tool for the characterization of depth profile concentrations in multilayered samples. A modeling program called ANDEN has been developed for simulating GI-XRF data for layered thin films [1]. ANDEN was used as one of the tools to study the dependence of dopants distribution with magnetic behavior in Diluted Magnetic Semicond...

We present a new route for mass-production of B and P codoped all-inorganic colloidal Si nanocrystals (NCs) from hydrogen silsesquioxane (HSQ). Codoped Si NCs are grown in glass matrices by annealing mixture solutions of HSQ and dopant acids, and then extracted from the matrices by hydrofluoric acid etching. The free-standing NCs are dispersible in methanol without any surface functionalization...

Photocatalytic degradation of fast green using pure and N-S codoped bimetal nanoparticles CeCdO3 has been studied. The CeCdO3 nanoparticles were synthesized by wet precipitation method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and FTIR. The rate of photocatalytic reaction was examined spectrophotometrically using pure and N, S-codoped catalyst. The effect ...

Nonradiative energy transfer (NRET) is an alternative excitation mechanism in colloidal quantum dot (QD) based electroluminescent devices (QLEDs). Here, we develop hybrid highly spectrally pure QLEDs that facilitate energy transfer pumping via NRET from a phosphorescent small organic molecule-codoped charge transport layer to the adjacent QDs. A partially codoped exciton funnelling electron tra...
