Thermal Effect of Er3+Ions Embedded in Smart Nano-Composite Oxide Material Prepared by Sol-Gel Technique

“…An important effect on the densification processes was achieved by well particle size distribution. Nanostructure phase and a narrow size distribution aid in obtaining dense and homogeneous materials [25,26], these results are compatible with the observed FTIR data.…”

“…The emission is induced by defects, where the pores disappear, hydroxyl content decreases and the nanocomposite density increases affecting the co-operative-up-conversion emission spectra [26,32].…”

Synthesis of Fe2O3 concentrations and sintering temperature on FTIR and magnetic susceptibility measured from 4 to 300K of monolith silica gel prepared by sol–gel technique

“…They were grown by increasing the sintering temperature up to 1150 1C, showing the presence of (hematite) a-, which is the most stable form observed at higher temperature, and/or e-Fe 2 O 3 phases. Structural modification of amorphous pure silica into a-crystobalite has been observed only at higher temperature 1150 1C, as we reported previously [25].…”

“…Inorganic matrix as a host for nanoparticles can be an effective form to prepare particles with uniform size and to determine morphology having control over the homogeneous dispersion of ultrafine cluster of metal oxides. Nano-sized materials, as well as fine magnetic particles, have received great attention during the last decade [4][5][6][7]. The physical properties of nano-structured materials differ considerably from their bulk counterparts, thus making applicability of ferrites even more versatile.…”

Influence of Deposition Temperature on Nanocrystalline CdS Thin Films: Application in Solar Cells as Antireflection Coatings

“…Chemical bath deposition is a method of growing thin films of certain materials on a substrate immersed in an aqueous bath containing appropriate reagents at temperatures ranging from room temperature to 100 °C. It has been identified as a low process suitable for the preparation of large area thin films [8]. Chemical bath deposition (CBD) method has attracted much attention since it is conformed as a simple and promising technique to obtain device quality films.…”
