Abstract

Ag-109 MAS-NMR spectra of AgI-based glasses containing frozen α-AgI nanocrystals were measured extensively for AgI-Ag₂O-M_xO_y (M_xO_y = B₂O₃, GeO₂) systems. The spectrum of α-AgI frozen glass composite observed at room temperature was separated into three components, which were ascribed to glass matrix, α-AgI nanocrystals and crystalline β-AgI. The temperature dependencies of the spectra suggest the formation of more α-AgI nanocrystals by heating.
