Glass ceramics of composition 34SiO 2 -29Al 2 O 3 -25CaO-12CaF 2 (wt.%) was made by conventional melting and quenching process using either normal or nano-SiO 2 respectively. The glasses were characterized by differential thermal analysis (TG/DTA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM)...
ZnOis one of the most promising materials for optoelectronic devices for UV spectral range because of its wide and direct bandgap (3.37 eV) and high exciton binding energy (60 meV). The generation of multiphoton absorption (MPA) induced luminescence in ZnO by highly intense fs-lasers in near infrared offers one effective route for optical excitation. Therefore, much attention has been paid recently...
A nanocomposite of functionalized 2.5 wt.% carboxylated multiwalled carbon nanotubes (MWCNTs) /polyaniline (PANi) is synthesized using in situ chemical polymerization method. MWCNT is coated by using in-situ chemical polymerization of Polyaniline polymer. Structure and morphology of nanocomposite is characterized, using X-ray diffraction pattern (XRD), scanning electron microscopy (SEM) and transmission...
