were confirmed by X-ray diffraction technique(XRD) with variable microwave temperatures. XRD analysis showed that the phosphors prepared by MA-CCP method at the temperature of 750, 900oC, respectively......
used to analyze the phase transformation as a function of temperature, and the Rietveld refinement was used in order to characterize the materials obtained structurally. The average crystallite size......
ranges from 1.79 to 3.05 g RE2 O3 per100 g electrolyte and the corresponding mole concentration is 0.33%-0.87%. RE2 O3 solubility increases with increasing temperature and REF3 concentration......
% LaH3,was prepared by ball milling LiBH4 and hydrogenated LaMg2 Ni and Mg2 Ni powder mixture, followed by heat treatment at 573 K. The onset dehydrogenation temperature of the composite is reduced......
. The conductivity increases with measurement temperature and Tm doping. Optical spectra of the ZnO samples were measured in UV-Vis range and the band gap(Eg) is found to be 3.35 eV.关键词:......
of nitric acid leaching of cerium was investigated for the oxidation roasted Baotou mixed rare earth concentrate. The effects of leaching temperature, HNO3 concentration, liquidesolid ratio(L/S)and stirring......
nanophosphors. The electric dipole-dipole interaction is found to be responsible for the concentration quenching. The temperature dependent behaviour of the two green thermally coupled levels of the Er3+ ions......
by magnesium bicarbonate solution was investigated with the self-designed constant interfacial area cell. Besides, the effects of stirring rate, temperature, specific interfacial area and concentration......
International de l’Eclairage(CIE) chromaticity diagram reveals blue-green color emission. The correlation color temperature(CCT) value is found to be around ~9793 K. The obtained results suggest......
enhancement of the phosphorescence emission intensity in DESs as polar and weakly coordinating solvent.Several DESs stabilize the lanthanide ion luminescence against changes in temperature and moisture......
