The development of new functional materials requires cutting-edge technologies for incorporating different functional materials without reducing their functionality.
Synthesis
and detailed characterization of lithium-incorporated
(0–20% of Li loading) MgO nanocrystals are presented. High
surface reactivity arises due to the presence of facets and kinks
at the surface of the particles. Fourier transform infrared spectroscopy
(FTIR) showed that the presence of surface modes with peak shift related
to the difference in the electronegativity of Li ions and the formation
of extra modes for low loading of Li. For LiMgO particles, interband
transitions due to the F
+
centers and the surface Li
x
O species
are observed. Formation of F
+
centers is consistent with a decrease in the lattice parameter
as a function of Li loading. A significant increase in the magnetic
moment of the LiMgO nanoparticles is discussed in terms of the presence
of oxygen vacancies and Li-rich surface regions. Three new bands in
the higher frequency range are observed for LiMgO nanoparticles. Overall,
studies revealed that the surfaces of the particles are not the same
for low and high loadings of Li.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
