UNLABELLED Undoped ZnO, Ce-doped ZnO, and (Li, Ce)-codoped ZnO nanophosphors were prepared by a sol-gel process. The effects of the additional doping with Li ions on the crystal structure, particle morphology, and luminescence properties of Ce-doped ZnO were investigated by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, electron paramagnetic resonance spectro...

In today’s world of electronics, nanomaterial applications pose a challenge. The spin coating approach was used to create nanostructured ZnO with wurtzite structure in recent study. Antimony doping, aluminum, and antimony codoping 2.0 percent were make these films. impact doped codoped films on structural, optical properties, morphological has been examined using variety characterization approa...

White organic light-emitting devices OLEDs consisting of ambipolar 9,10-bis 2 -naphthyl anthracene ADN as a host of blue-emitting layer EML were investigated. A thin codoped layer of yellow 5,6,11,12-Tetraphenylnaphthacene rubrene served as a probe for detecting the position of maximum recombination rate in the 4 ,4 -bis 24N ,N-diphenylamino phenyl vinyl biphenyl DPAVBi doped-ADN EML. Due to th...

The upconversion luminescence properties of Yb3+/Tm3+-codoped oxyfluoride tellurite glasses under 980 nm excitation are investigated experimentally. The intense blue and relatively weak red emissions centered at 475 and 649 nm corresponding to the transitions G4 → H6 and 1

Conductive polypyrrole–polyaniline/TiO2 nanocomposites (PPy–PANI/TiO2) were prepared by in situ oxidative copolymerization of pyrrole and aniline monomers in the presence of TiO2. For comparison studies, polypyrrole/TiO2 (PPy/TiO2) and polyaniline/TiO2 (PANI/TiO2) were also prepared. The samples were characterized by X-ray diffraction, transmission electron microscopy, UV-vis diffuse reflectanc...
