Ageing effects in Ag-Ge-Se bulk glasses
Glasses of composition Agx(Ge0.25Se0.75)100-xand Agx(Ge0.25Se0.75)100-xdoped with 0.5 at% of 57Fe were analyzed with the aim to evaluate if their structure evidences any effect of ageing, for thousands of hours at room temperature and/or hundreds of hours for sub-Tg thermal treatments. Strong agein...

| Sumario: | Glasses of composition Agx(Ge0.25Se0.75)100-xand Agx(Ge0.25Se0.75)100-xdoped with 0.5 at% of 57Fe were analyzed with the aim to evaluate if their structure evidences any effect of ageing, for thousands of hours at room temperature and/or hundreds of hours for sub-Tg thermal treatments. Strong ageing effects were observed by means of Mössbauer spectroscopywhereas Raman spectroscopy contributed to identify the origin of these effects. |
