Analyzing the dependencies, the conditions suitable for production of the nanoparticles are determined. In particular, it is found that low-density plasmas where electrons have the Druyvesteyn energy distribution are more favorable for the production of nanoparticles than high-density plasmas with the Maxwellian distribution for electrons. The production of nanoparticles in the case of plasma with large density and radius of nanoparticles is not intensive because of small density of C2H- anions. These conclusions are in a good agreement with experimental measurements.","PeriodicalId":239169,"journal":{"name":"2018 IEEE 8th International Conference Nanomaterials: Application & Properties (NAP)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126109674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Samarium concentration was varied in the range of 0.03, 0.1, 0.2, 0.3, 0.5, 1.0, 1.5 and 3 wt.%. It has been found that MgAl2O4 nanopowders are in the amorphous state when the samarium impurities are missing and the presence of samarium impurities even of the smallest concentration is the necessary condition for the formation of the crystalline spinel phase. Depending on the synthesis temperature (Ts) and samarium content, the nanoparticle size varies: from 5 nm to 6 nm at Ts = 700 °C and from 7 nm to 15 nm at Ts = 1000 °C. According to the X-ray phase analysis, it has been revealed that the nanoparticle sizes get smaller when the samarium concentration increases. Under the luminescence study, it has been found that there is an optimal set of the «samarium concentration - nanoparticle sizes“ parameters at which the luminescence intensity reaches an extreme value. The half-width of the most intensive 4G5/2 - 6H7/2 line became narrow under additional heat treatment. It evidences that Sm ions are situated in a near-surface layer in the just prepared nanoparticles and they get into inter-grain boundaries after additional annealing.","PeriodicalId":239169,"journal":{"name":"2018 IEEE 8th International Conference Nanomaterials: Application & Properties (NAP)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123653440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magneto-optical imaging reveals that flux moves along a set of parallel and perpendicular lines, while optical microscopy does not show any features on the surface that may be linked to this effect. In contrast, scanning electron microscopy registers sub-micron fractures in the superlattices corresponding to these flux lines, but the magnetic flux channels are much wider than the width of these fractures. To further clarify the origin of flux channels, electrical transport measurements on the superlattices have been performed. Their current-voltage characteristics reveal the presence of distinctive branches related to the flux motion along the selective channels, following which magnetic flux crosses sample in a shortest and least resistive way. The application of very large current overheated the superlattice along these channels, evaporating superconducting material and exposing, wider than in the superconductor, fractures in the substrate. It is concluded that motion of flux in the channels is controlled not only by the presence of nano-fractures in YBa<inf>2</inf>Cu<inf>3</inf>O<inf>7-</inf><inf>δ</inf>/PrBa<inf>2</inf>Cu<inf>3</inf>O<inf>7-</inf><inf>δ</inf>, but also by stress developed in the superconducting material due to the fracturing of the substrate.","PeriodicalId":239169,"journal":{"name":"2018 IEEE 8th International Conference Nanomaterials: Application & Properties (NAP)","volume":"68 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130400470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The parameters of the sources are determined by fitting the analytical solution of these equations that describes the full emission of the system to the experimental results obtained. Having found the parameters of the auxiliary sources we can determine the temporal dependences of the radiation from excitons and biexcitons separately.
