We have investigated the adsorption of hydrogen multiwall carbon nanotubes synthesized by pyrolysis method using a lanthanum nickel storage alloy as catalyst. The mechanism La–Ni catalyst is discussed. In atmosphere and high-temperature process nanotube preparation, LaNi5 particle may be changed into an intermetallic compound Ni La analysis x-ray diffraction patterns energy-dispersive spectroscopy samples H2 uptake capacity about 5 wt % through to pressure 10 MPa. Using increases effect...
A color-tunable phosphor based on Tb[Formula: see text]/Eu[Formula: text] co-doped GdNbO 4 were synthesized by a traditional solid-state reaction method. X-ray powder diffraction (XRD), diffuse reflectance spectra, photoluminescence spectra and decay curves utilized to characterize the as-prepared phosphors. XRD result indicated that various concentrations single-doped phosphors well indexed pure phase. The host was proved be self-activated with broad absorption range from 200 nm 325 nm....
GdVO 4 :Eu3+ thin films were grown on Al2O3 (0001) substrates using pulsed-laser deposition. The crystallinity, surface morphology, and photoluminescence of the highly dependent deposition conditions, especially oxygen pressure substrate temperature. GdVO4:Eu3+ under optimized conditions indicated that is a promising for growth high-quality phosphor films. In particular, morphology show very similar behavior as function emitted radiation was dominated by red-emission peak at 620 nm this...
The effect of annealing temperature for carbon nanotubes (CNTs) in vacuum on its performance as a nickel hydrogen battery negative material is investigated by high resolution transmission electron microscopy (HRTEM), Raman, and discharge capacity. electrochemical CNTs can be improved treatment because few amorphous impurities defects annealed observations HRTEM Raman spectra. With the increase temperature, capacity increases initially then decreases. optimum around . Among with different...
Rare earth-doped Sr 3 Gd(PO 4 ) and emission color tunable phosphors Ce[Formula: see text]/Sm[Formula: text] co-doped have been synthesized by a traditional solid-state method. These were characterized X-ray diffraction (XRD), FE-SEM, diffuse reflectance spectra (DRS), photoluminescence lifetime measurements. The quenching concentration of ions in was about 9 mol.%. An effective energy transfer (ET) from to Sm[Formula: speculated the overlapped spectrum for peak excitation ions. It is...
