in one place and for first
time the formation process of Ag nanoparticles (NPs) on β-AgVO3 crystals, driven by an accelerated electron beam from an
electronic microscope under high vacuum. Synthesis and optical properties
of β-AgVO3 are reported, and the relationship between
structural disorder and photoluminescence emissions is discussed.
First principle calculations, within a QTAIM framework, have been
carried out to provide a deeper insight and understanding of the observed
nucleation and early evolution of Ag nanoparticles (NPs) on β-AgVO3 crystals. The Ag nucleation and formation is a result of
structural and electronic changes of the [AgO5] and [AgO6] clusters, consistent with Ag metallic formation.
