Luminescence of molecular silver clusters in oxyfluoride glasses
TL;DR: In this paper, the luminescence spectra of silver-containing oxyfluoride glasses have been investigated in the excitation spectral range of 360-480 nm, and it has been shown that silver in oxyfluoric glasses that contain no strong reducers and were subjected to heat treatment affecting redox processes exists in the form of neutral atoms and neutral molecular Ag2, Ag3, and Ag4 clusters.
