Abstract :
Ag-109 MAS-NMR spectra of AgI-based glasses containing frozen α-AgI nanocrystals were measured extensively for AgI–Ag2O–MxOy (MxOy=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.
