The luminescence mechanism of Ag13, AunAg13-n and Au13.

Caption

An energy diagram of (A) Ag13, (B) Au1Ag12, (C)Au3Ag10, and (D) Au13. Images of the hole and electron pairs. The Sr index is defined as the full space integration of a function (Sr(r)) describing the overlap between electron and hole distributions, and the D index is the distance between a hole and an electron center of mass.
