- ПубликацияТолько метаданныеEnhancement of spontaneous emission of semiconductor quantum dots inside one-dimensional porous silicon photonic crystals(2020) Dovzhenko, D.; Martynov, I.; Samokhvalov, P.; Osipov, E.; Lednev, M.; Chistyakov, A.; Nabiev, I.; Мартынов, Игорь Леонидович; Самохвалов, Павел Сергеевич; Осипов, Евгений Валерьевич; Чистяков, Александр Александрович; Набиев, Игорь РуфаиловичControlling spontaneous emission by modifying the local electromagnetic environment is of great interest for applications in optoelectronics, biosensing and energy harvesting. Although the development of devices based on one-dimensional porous silicon photonic crystals with embedded luminophores is a promising approach for applications, the efficiency of the embedded luminophores remains a key challenge because of the strong quenching of the emission due to the contact of the luminophores with the surface of porous silicon preventing the observation of interesting light-matter coupling effects. Here, we experimentally demonstrate an increase in the quantum dot (QD) spontaneous emission rate inside a porous silicon microcavity and almost an order of magnitude enhancement of QD photoluminescence intensity in the weak light-matter coupling regime. Furthermore, we have demonstrated drastic alteration of the QD spontaneous emission at the edge of the photonic band gap in porous silicon distributed Bragg reflectors and proved its dependence on the change in the density of photonic states.

This work is devoted to the study of the detection of trace amounts of 1,3,5-Trinitro-1,3,5-triazinane (RDX) in the form of particles localized in millimeter and submillimeter sizes using THz imaging with spectral resolution. As a result of the work, images of trace amounts of RDX in reflected THz radiation were obtained. The contrast in these images made it possible to detect single particles of the powdery substance. The difference in contrast for RDX and polyethylene (PE) in the obtained terahertz images makes it possible to use THz imaging with spectral resolution not only for detection, but also for the identification of chemical compounds.
- ПубликацияТолько метаданныеSol–Gel Derived Photonic Crystals BaTiO3/SiO2(2021) Kholov, P. A.; Karnilava, Y. D.; Lashkovskaya, E. I.; Raichenok, T. F.; Gaponenko, N. V.; Labunov, V. A.; Martynov, I. L.; Osipov, E. V.; Chistyakov, A. A.; Kargin, N. I.; Гапоненко, Николай Васильевич; Лабунов, Владимир; Мартынов, Игорь Леонидович; Осипов, Евгений Валерьевич; Чистяков, Александр Александрович; Каргин, Николай Иванович© 2021, Pleiades Publishing, Ltd.Abstract: It is shown for the first time that multilayer periodic BaTiO3/SiO2 structures formed by the sol–gel method are tunable photonic crystals with dependence of the photonic band gap from the temperature of the sample. The shift of the minimum in the reflection spectrum in the photonic band gap is observed from 616 to 610 nm in the sample-temperature range from +184 to +24°C, respectively, and is reproduced for several samples synthesized at a temperature of 450°C.
- ПубликацияТолько метаданныеPhoton counting mode for advanced real-time detection of bioaerosols(2021) Tkachuk, A. P.; Verdiev, B. I.; Alatirev, A. G.; Akmalov, A. E.; Chistyakov, A. A.; Kotkovskii, G. E.; Kuzishchin, Y. A.; Martynov, I. L.; Osipov, E. V.; Pashkevich, A. A.; Акмалов, Артём Эдуардович; Чистяков, Александр Александрович; Котковский, Геннадий Евгеньевич; Кузищин, Юрий Александрович; Мартынов, Игорь Леонидович; Осипов, Евгений Валерьевич; Пашкевич, Александра Андреевна© 2021 SPIECurrently, one of the most important application of flow cytometry is the real-time analysis of aerosols, in particular, to ensure biosafety. In most cases, such analysis is aimed at detecting fluorescent signals from aerosol particles corresponding to the light emission of tryptophan and nicotinamide adenine dinucleotide (NADH). Further development of the method is largely related to the improvement of the light detecting systems for recording and processing of fluorescence and scattered light signals. In this work, a comparative analysis of flow cytometers for bioaerosols detection based on photo-multiplier tubes (PMT) and avalanche photodiodes (APD) operating in analog and photon-counting modes was carried out. The limit of detection (LOD) of bioaerosols, response time and ability to detect particles with low scattering and fluorescence cross section were calculated and examined. The calculations were carried out for the well-known optical scheme of fluorescence detection based on discrete photodetectors and dichroic mirrors combined with an air flow chamber equipped with elliptical and spherical mirrors. An ultraviolet light emission diode (LED) was used as a model source of exciting radiation. To estimate the optical properties of aerosol particles, experimental results obtained for a model bovine serum albumin bioaerosol and published data on various other bioaerosols were used. The calculation of the total number of fluorescent photons, emitted by particles of various sizes while passing the flow chamber was carried out. The obtained data were compared with parameters of photodetectors operating in analog and photon-counting modes. The critical particle size was determined for the effective registration in a photon-counting mode. Considering the size distribution of aerosol particles, it was concluded that application of the photon-counting mode will reduce the LOD of bioaerosols by more than an order of magnitude.
