Full textNy forskning har visat att polymerbaserade nanokompositer (PNCs) har utformats för att förbättra strömbrytares förmåga att undvika ljusbågar vid överslag. PNCs är en kombination av nanostora oorganiska nanopartiklar (NP) och polymerer, som har öppnat upp för ny utveckling inom materialvetenskap och tekniska tillämpningar. Oorganiska NP väljs baserat på deras fysikaliska och kemiska egenskaper som kan hjälpa PNCs att motverka elektriska ljusbågar effektivt. I synnerhet, presenterade vi PNCs tillverkade genom användning av CuO, Fe3O4, ZnO och Au NP i en poly (metylmetakrylat) (PMMA)-matris via in situ-polymerisationsmetod, nyligen utvecklad för att undvika NP-agglomerering, vilket leder till god rumslig fördelning i polymermatrisen. Därför har flera prover med olika vikt% av NP i PMMA-matris tillverkats. Dessa PNCs har utvärderats i detalj för NP-morfologi, interaktion mellan NP och polymermatris, och strålnings- och värmeenergiabsorption. I nästa skede testas PNCs för att bestämma deras förmåga att undvika ljusbågar och påverkan på de elektriska ljusbågarna av 1,6 kA strömstyrka, genererade med hjälp av en specialdesignad test-set-up. När PNCs interagerar med de elektriska ljusbågarna, genererar de ablation av kemiska ämnen mot kärnan i den elektriska ljusbågen, vilket resulterar i nedkylning av ljusbågen på grund av starka temperatur- och tryckgradienter i området. Denna avhandling visar för första gången att dessa konstruerade PNCs är lätta att framställa, reproducerbara, och kan användas för att förbättra avbrottsprocessen för ljusbågen i elektriska kopplingstillämpningar.

Full textThe present work covers the fabrication and optical investigation of semiconductor microcavities for Bose–Einstein condensation (BEC) of exciton-polaritons. These microcavities consist of highly reflective distributed Bragg reflectors (DBR) surrounding a ZnO-cavity as active medium. In the first step, the growth of DBRs was optimised with respect to exact thickness control and high reproducibility. For the active material, several growth strategies have been pursued, in order to optimise the conditions for the growth of planar thin films by pulsed laser deposition. Techniques like annealing or ion beam smoothing were successfuly applied in order to either improve the electronic properties or decrease the roughness of the ZnO-cavity layer. Furthermmore, a successful technology was developed in order to coat highly-crstalline free-standing ZnO nanowires with concentrical DBR shells. All samples have been investigated regarding their roughness and crystallinity as well as their optical properties. For the latter spatially and/or angular-resolved photoluminescence spectroscopy and reflection measurements have been carried out. Thereby, the strong coupling regime – being prerequisite for BEC – could be demonstrated in almost all of the synthesized structures. For the nanowire-based microcavities hints for an enhanced coupling strength have been found. In one of the planar samples, showing the high quality factor of 1000, the formation of BEC almost up to room temperature was observed and was studied as a function of temperature and detuning. Negative detuning was found to be mandatory for the formation of a BEC in ZnO-based microcavities. The distinct momentum- respective in-plane wavevector distribution of the condensate polaritons revealed a strong dynamic character of these particles at low temperatures

The p-GaN/n-ZnO nanorods light-emitting diodes (LEDs) with near-ultraviolet electroluminesce (EL) based on ZnO:carbon dots composites were realized. The emission intensity can be tuned by adjusting the concentrations of carbon dots in the precursors of ZnO NRs. The enhanced light output power of energy efficient p-GaN/n-ZnO composite nanorods LEDs reported here can be possibly attributed to the important role of carbon dots in ZnO/carbon dots composite nanorods acting as a conducting network in the ZnO active matrix that leads to the surface plasmon(SP) enhanced light emission and the improved electrical conductivity. Our work proposed a simple route to fabricate efficient near-ultraviolet LEDs assisted by additions of carbon dots.

This dissertation describes the synthesis of low-dimensional nanostructures via a series of facile aqueous solution methods at low temperature (<2000C). We started with the fabrication of vertically aligned ZnO nanorods (NRs) on aluminum-doped zinc oxide (AZO) substrates by a single-step aqueous solution method. In order to strengthen photoluminescence (PL) property, ZnO nanorod arrays were annealed at various temperature. We found that the annealing temperature strongly affects both the near-band-edge (NBE) and visible (defect-related) emissions, this eventually leads to the understanding of the optimum annealing condition to achieve enhanced optical properties. Some important findings were found from the PL study, for example, the enhancement of NBE is due to the activation of radiative recombinations associated to hydrogen donors (Ho), and the reduction of visible emission is mainly because of the annihilation of OH groups from the ZnO surface. This interesting finding motivated us to synthesis ZnO hybrids so that we can exploit its promising optical properties in the photocatalysis application under UV or visible light illumination. Next, the plasmonic Au nanoparticles were deposited on the ZnO nanorod arrays to fabricate a noble metal/semiconductor hybrid structures. Interestingly, this Au/ZnO platform exhibits amazing UV-Vis photocatalytic activity alongside the strong luminescent properties. The visible-light active photocatalysis is assisted by localized surface plasmon resonance (LSPR) excitations while the strong absorption and charge separation under UV irradiation is responsible for enhanced catalytic performance. Besides, the enhancement in optical properties is mainly due to local field enhancement effect and the coupling between exciton and LSPR. For the first time, we showed that the plasmonic enhancement of photocatalytic performance is not necessarily a trade-off for enhanced near-band-edge emission in Au/ZnO. The excellent emission property and photocatalytic activity results motivated us to combine low-dimensional ZnO nanostructures with some earth-abundant two-dimensional (2D) materials as a replacement of expensive noble metals. Thus, we prepared heterodimensional nanostructures of 2D ultrathin MoS2 nanosheets interspersed with ZnO nanoparticles by using a facile two-step method. Foremost sonication-aided liquid phase exfoliation technique (LPE) was used to exfoliate ultrathin MoS2 nanosheets in ethanol/water solvent, subsequently a wet chemical process was employed to realize interspersion of ZnO nanoparticles onto the MoS2 surface. In this case, ultra-thin MoS2 nanosheets acted as the support for the nucleation of various concentrated small ZnO dots. The photocatalytic activity of the ZnO/MoS2 nanocomposites was performed with organic dye pollutants and tetracycline, a common antibiotic, as a model compound under visible-light irradiation. We found extremely high catalytic efficiency with these composites under visible light, where the reaction rate of pollutant degradation is about eight times higher than those of commercial P25-TiO2 photocatalysts. This outstanding photocatalytic activity of the heterodimensional hybrids results from the synergetic effects of ZnO and MoS2. Most importantly, the heterojunction formation between ZnO and MoS2 facilitates the separation of photogenerated active charge carriers, leading to the enhancement of photocatalytic performance. Moreover, a tentative mechanism for photocatalytic degradation was proposed in this report, which can provide valuable insights for the exploration of cost-effective nanoscale hybrids constructed from atomically thin layered materials. Finally, we have synthesized mesoporous C-ZnO nanostructured via a facile one-step hydrothermal process, and then liquid-exfoliated 2D MoS2 nanosheets were integrated with the C-ZnO through simple thermal treatment to obtain C-ZnO@MoS2 composites. The photocatalytic activity was evaluated under visible light irradiation and we found the significant enhancement in photodegradation of organic dye molecules by the introduction of MoS2 nanosheet on C-ZnO. Such a significant photoactivity could be attributed to the MoS2 nanosheets that strengthen the visible-light absorption to create the electrons and holes in the system and their favourable separation occur by the electron transaction between ZnO, and MoS2. The synergistic effect between carbon, MoS2 and ZnO makes C-ZnO@MoS2 composites a suitable visible-light driven photocatalyst.
