Выполнен расчет параметров электрического поля и оптических свойств вблизи нанозвезд разных размеров. Параметры рассчитаны методом конечных разностей во временной области. Определены оптимальные размеры нанозвезд при изменении толщины поверхностных слоев для получения максимальных значений рассеяния и дальнейшего использования исследованных структур гигантского комбинационного рассеяния света в экспериментах. Выполнен синтез нанозвезд, исследованы их оптические и морфологические свойства, а также проведена функционализация кварцевых поверхностей и созданы прототипы сенсоров с целью дальнейшей оценки усиления сигнала (комбинационного рассеяния света). По результатам математического моделирования определены оптимальные размеры для синтеза нанозвезд, который осуществлен двухступенчатым химическим методом с использованием зародышевых частиц. Для проведения экспериментальной части по получению спектров гигантского комбинационного рассеяния применен спектрометр Centaur U (ООО «НаноСканТехнология», Россия). Спектрометр оснащен тремя источниками: He-Ne лазером (λ = 632,8 нм, 17 мВт) и двумя DPSS лазерами (λ = 532 нм и λ = 473 нм, 50 мВт). В процессе проведения эксперимента использованы He-Ne лазер и DPSS лазер с длиной волны λ = 532 нм. В оптическую схему спектрометра включен микроскоп Olympus BX41 (Olympus, Япония) с объективом 100× (NA 0,9) для позиционирования луча и сбора рассеянных фотонов. Монохроматор спектрометра имеет фокусное расстояние 800 мм, голографическую дифракционную решетку 300 шт/мм и снабжен термоэлектрическим охлаждаемым ПЗС-детектором 1024 × 256 пикселов (Andor Tech., Великобритания).</p></sec><sec><title>Практическая значимость</title><p>Практическая значимость. В результате работы получены функционализированные наночастицы поверхности — прототипы оптических сенсоров.

Полученные результаты могут служить основой для получения необходимых размеров нанозвезд в методах контролируемого химического синтеза коллоидных наночастиц.

Surfaces functionalized with nanoparticles, prototypes of optical sensors, have been obtained. It is shown that the obtained experimental Raman signal enhancement from the dye rhodamine 6G (R6G) can be at least order 104. The paper presents the results of calculation, synthesis and study of the optical and morphological properties of such structures. A complex method for creating and evaluating the optical properties of planar nanostructures and evaluating their optical properties is proposed. The method includes the approaches based on mathematical modeling using finite differences in the time domain (FDTD - FiniteDifference Time-Domain) evaluating electromagnetic field strengths near the surfaces of star-shaped gold nanoparticles in colloidal solutions and on a silicon surface. During the simulation, we studied such parameters as the particle size, the wavelength of the exciting radiation, and the dependence of the effective amplification of the electromagnetic field on the morphological parameters of the star. The theoretical approach to the calculation of such structures is shown to be promising for the subsequent chemical synthesis described in the article and the study of optical properties. In this paper, a theoretical calculation of the parameters of the electric field and optical properties is carried out near star-shaped nanoparticles of varying sizes. These parameters were calculated by the finite difference method in the time domain. The task included finding the optimal sizes of nanoparticles as well as varying the thickness of the surface layers in order to obtain the maximum scattering values and further use of similar structures in SERS experiments. Also, within the framework of this work, syntheses of star-shaped nanoparticles was carried out, their optical and morphological properties were studied, quartz surfaces were functionalized with nanoparticles, and sensor prototypes were created in order to further assess the Raman signal amplification. Based on the results of mathematical modeling, the optimal sizes for the synthesis of star-shaped NPs were determined. Synthesis of NPs was carried out by a chemical method using seeds. To carry out the experimental part, SERS spectra were obtained using Centaur U spectrometer (OOO NanoScanTechnology, Russia). The spectrometer was equipped with three different laser sources: 632.8 nm He-Ne laser (17 mW), 532 nm and 473 nm DPSS lasers (45 mW). During the experiment, a He-Ne laser with λ = 632 nm and DPSS laser with λ = 532 nm were used to match the excitation of the plasmon maximum for the nanostars. The optical scheme of the spectrometer included an Olympus BX41 microscope (Olympus, Japan) with a 100× objective (NA 0.9) for positioning the beam and collecting scattered photons. The monochromator of the spectrometer had a focal length of 800 mm. A holographic diffraction grating of 300 gr/mm, and was equipped with a 1024×256 pixel thermoelectric cooled CCD detector (Andor Tech., UK). As a result of the paper, surfaces functionalized by nanoparticles were obtained prototypes of optical sensors. It is shown that the experimental gain of the Raman signal can be no less than 104 times. The presented data will serve as the basis for obtaining the required sizes of nanostars in the methods of the controlled chemical synthesis of colloidal nanoparticles. The results presented in the article can be applied to the development of biocompatible and highly sensitive optical sensors based on the effect of Raman scattering of light.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спектроскопия комбинационного рассеяния света</kwd><kwd>нанозвезда</kwd><kwd>плазмон</kwd><kwd>оптический сенсор</kwd><kwd>моделирование оптических свойств</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Raman spectroscopy</kwd><kwd>nanostar</kwd><kwd>plasmon</kwd><kwd>optical sensor</kwd><kwd>modeling of optical properties</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках Соглашения с Минобрнауки Российской Федерации № 75-02-2022-872.</funding-statement><funding-statement xml:lang="en">The study was supported by the Project of the state assign of the Ministry of Education and Science of the Russian Federation No. 75-02-2022-872.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Israël M., Schwartz L.
