| Description: | It is shown that the vacuum poling of soda-lime silicate glass followed by silver-for-sodium ion exchange results in the formation of silver nanoparticles (NPs) in subcathode region of the glass. The latter was confirmed by the presence of silver NPs’ localized surface plasmon resonance peak in optical absorption spectra of the samples. The NPs had grown in 2 um thick subsurface region of the glass, which was confirmed by etching the cathode side of the sample. The possibility of forming a 2D-structured pattern from silver NPs that repeats the relief of the cathode electrode used for poling, has also been demonstrated. A hypothesis about the reduction of silver ions during the ion exchange by sodium atoms penetrated the glass from the cathode during poling in vacuum is proposed. Показано, что вакуумный полинг щелочно-силикатного стекла и последующий серебряно-натриевый обмен приводят к образованию серебряных наночастиц (НЧ) в подкатодной области стекла. Продемонстрирована возможность создания 2D-структурированных паттернов, образованных серебряными НЧ, повторяющих рельеф катодного электрода, используемого при полинге. Предложена гипотеза о восстановлении ионов серебра в процессе ионного обмена атомами натрия, проникшими в стекло с катодной стороны в процессе вакуумного полинга. |
