The electronic and optical properties of BiFeO3 (BFO) crystal are investigated at 300 K and 1000 K, via density functional theory (DFT).The relative crystal
Ti1.4V0.6Ni alloys containing quasicrystal phase compositing with x wt.% LiBH4 (x =0, 1, 2, 3) were prepared by mechanical ball-milling for the first time.T
Low-coordination Au sites have been proved to play a key role in defining the catalytic activity of Au nanoclusters (NCs).At the present time, it is still o
Electronegativity (EN) is a chemistry concept initially defined by Pauling as "the power of an atom in a molecule to attract electrons to itself" in 1932.Th
As a novel class of inorganic phosphors, oxynitride and nitride luminescent materials have received increasing attention because of their excellent optical
We show that core/shell structure, NaYF4∶Yb,Er/Tm@CaF2, that the shell is epitaxial growth over the core, is a good way to isolate the emitters from the su
