Electron microscopic investigation of yttrium aluminum garnet powders Y3Al5O12, synthesized by sol–gel method

Green-emitting Y3Al5O12: Tb phosphor materials have been widely studied because of their high luminescence efficiency and stability under the conditions of high irradiance with an electron beam. In this paper, Green-emitting phosphor of yttrium aluminum garnet (Y3Al5O12 or YAG) doped with Tb3+, Ce3+ and Gd3+ was synthesized by sol-gel method. By means of TG/DSC, XRD, and photoluminescence (PL) performance, the sintering condition and its influence on the powder’s emitting performance were studied. The experimental results showed that, Y2.8Tb0.12 Ce0.08-x GdxAl5O12 synthesized by sol-gel method was a kind of phosphor of good performance. When the value of x was set at 0.04, the best emitting performance was obtained. The Y3Al5O12: Tb, Ce, Gd particles had fine size, spherical shape, filled morphology, high crystallinity, and good brightness.

High temperature superconducting (SC) 2212 BiSrCaCuO nanoparticles were prepared by Sol-Gel method. Precursor was characterized by X-ray diffraction (XRD) and scanning Electron micrography. The superconductor nanocomposites were fabricated by nanoparticles of the SC powder with NR/LLDPE blends. The superconductive properties of the sintered samples and the nanocomposites were studied. Transition to a superconducting state around 88K appeared in the parent sample and in the composites. The scanning electron microscopic investigation of the nanostructures of SC polymer ceramic nanocomposites shown nanoscale dispersion of BSCCO in the polymer phase uniformly.

Nano-sized LiNi0.5Mn1.5O4 spines is prepared by a sol-gel reaction at 800 °C in air. Scanning electron microscopic (SEM) image indicates that LiNi0.5Mn1.5O4 has cubic spinel structure with small and homogeneous particles (about 300 nm). Electrochemical test shows that the prepared LiNi0.5Mn1.5O4 delivers up to 125 mAh g− 1at 0.2 C, and the capacity retains 110 mAh g− 1 at 0.5 C after 50 cycles.
