Microstructure and thermally stimulated depolarisation currents of SLS glass partially substituted by copper

TSDC spectroscopy of relaxational and interfacial phenomena

“…Glass materials are popular objects for TSDC investigations [165][166][167][168][169][170][171][172][173][174][175][176][177][178][179][180][181][182][183] of the mechanisms of dipolar polarisation and relaxation, dc electronic and ionic conductivity. Dutt and Day [165] and Dutta and Day [166] analysed the origin of TSDC in oxide glasses.…”

“…peak had an activation energy less than that for dc conduction, and its behaviour was consistent with dipole polarisation. A series of works was devoted to glasses with Cs, Fe, Na, and Cu phosphates [167][168][169][170][171][172], alkali borate glasses [173][174][175] and multi-component glasses [176][177][178], especially their dc conductivity and the effects of composition and structure on the relaxation mechanism. The effects of irradiation of glasses [179] and defects [180] were also studied by the TSDC technique.…”

Colloidal copper in soda‐lime silicate glasses characterised by optical and structural methods

“…Subsequent thermal treatment in a hydrogen atmosphere results in the formation of atoms and colloidal metal particles. It has been shown previously [3,4] that the presence of these nanoparticles affects the optical and electrical properties of soda -lime silicate (SLS) glasses exchanged with copper. Although copper nanoparticles of different size have been detected at the beginning and at the end of the exchanged layer [5], the spatial distributions of the particles' size and shape were not determined.…”
