This paper presents a study of nanoclusters obtained by electrochemical deposition (ECD) of zinc in the a‐SiO2/Si‐n track template. The nanoporous SiO2 layer on Si substrate (track template) has been created by irradiation with swift Xe ions and further etching in HF solution. The morphology of SiO2/Si‐n track templates and precipitated Zn‐based clusters are examined using a scanning electron microscope JSM 7500F. The crystallographic structure of the Zn‐based precipitates was investigated by means of X‐ray diffraction (XRD). X‐ray analysis is carried out on a D8 ADVANCE ECO X‐ray diffractometer. The Bruker AXSDIFFRAC.EVAv.4.2 software and the international ICDD PDF‐2 database are used to identify the phases and study the crystal structure. From XRD data, it has been found the formation of three crystalline phases of zinc oxide nanocrystals electro‐deposited into SiO2/Si track template: wurtzite, sphalerite, and rock salt structures. Wurtzite is obtained on an amorphous surface of silicon dioxide. Possible mechanisms of ZnO formation instead of metal Zn nanocrystals are discussed.

“…Он наиболее технологичный, так как поз-воляет контролировать морфологию, структуру, состав и соответственно магнитные свойства наноструктур за счет изменения ряда внешних параметров: температуры, состава и кислотности электролита, напряжения на элек-тродах и времени осаждения [6,[9][10][11]. В настоящее вре-мя довольно хорошо отработаны механизмы получения магнитных нанопроволок с использованием подложек из Si [12], Al 2 O 3 [13] и SiO 2 [14]. Однако получение нанотрубок на таких подложках ограничено особенно-стью методики синтеза [15,16].…”

На базе полиэтилентерефталатовых темплатов методом электрохимического осаждения синтезированы железные нанотрубки с аспектным соотношением порядка 100. Методами сканирующей электронной микро-скопии, энергодисперсионного анализа, просвечивающей электронной микроскопии, дифракции электронов, рентгеноструктурного анализа и газопроницаемости проведено детальное исследование структурных и морфологических особенностей нанотрубок. При помощи вибрационной магнитометрии и мессбауэровской спектроскопии определены основные магнитные параметры, а также их зависимость от температуры.

“…Выбор оптимальной формы и взаимного расположения НС позволяет по-лучать необходимое усиление сигнала в ГКР-спектроскопии, а контролировать форму НС можно за счет использования пористых шабло-нов при синтезе плазмонных НС. В этом случае диаметр поры определяет процесс нуклеации, форма поры задает направление роста кристал-литов, а время синтеза -степень разрастания НС [11][12][13]. С точки зрения усиления оптиче-ских свойств наиболее интересными являются структуры, имеющие наибольшее количество «горячих точек», которые образуются на неров-ностях поверхности и в местах соединения от-дельных элементов структуры [16].…”

Surface-enhanced Raman scattering is a powerful method used in chemoand biosensorics. The aim of this work was to determine the relationship between the signal of Surface-enhanced Raman scattering and the shape of silver nanostructures under the influence of laser radiation with different power.Plasmonic nanostructures were synthesized in silicon dioxide pores on monocrystalline silicon n-type substrate. The pores were formed using ion-track technology and selective chemical etching. Silver deposition was carried out by galvanic displacement method. Synthesis time was chosen as a parameter that allows controlling the shape of a silver deposit in the pores of silicon dioxide on the surface of single-crystal n-silicon during electrodeless deposition. Deposition time directly effects on the shape of metal nanostructures.Analysis of the dynamics of changing the morphology of the metal deposit showed that as the deposition time increases, the metal evolves from individual metallic crystallites within the pores at a short deposition time to dendritic-like nanostructures at a long time. The dependence of the intensity of Surface-enhanced Raman scattering spectra on the shape of the silver deposit is studied at the powers of a green laser (λ = 532 nm) from 2.5 μW to 150 μW on the model dye analyte Rodamin 6G. The optimum shape of the silver deposit and laser power is analyzed from this point of view design of active surfaces for Surface-enhanced Raman scattering with nondestructive control of small concentrations of substances.The silver nanostructures obtained in porous template SiO2 on n-type silicon substrate could be used as plasmon-active surfaces for nondestructive investigations of substances with low concentrations at low laser powers.
