The sol–gel technique is a highly flexible technique for fabrication of oxide glasses, and various researchers have previously reported fluorescence studies of Er-doped sol–gel films and monoliths. Here we report the fabrication of Er-doped strip-loaded sol–gel silicate waveguides, using a silica–titania–alumina host composition, and Er concentrations up to f1.1=10 Er rcm, for possible applicat...
Doped and undoped nanostructured titanium dioxide was synthesized via a sol–gel method under varying conditions to determine the effects of neodymium ion doping on the titania lattice. Specifically, the effects of doping on the anatase to rutile phase transformation were studied. Samples were analyzed by a variety of techniques, including X-ray diffraction, Rutherford back-scattering spectrosco...
This paper reviews the recent progress in the preparation of oxide-based and heteroatom-doped particles. Surfactant-templated oxide particles, e.g. silica and titania, are possible candidates for various potential applications such as adsorbents, photocatalysts, and optoelectronic and biological materials. We highlight nanoporous oxides of one element, such as silicon or titanium, and those con...
Abstract Rare earth metal cerium-doped titania nanoparticles (titanium dioxide [TiO 2 ]) were produced utilizing a low-cost and straightforward sol–gel technique, its enhanced photodynamic anticancer activity was tested on Y79 retinoblastoma cancer cells. The structural, optical, morphological, activity, cytotoxicity of pure TiO (Ce-doped ) investigated. In X-ray diffraction (XRD) measurements,...
