A highly tunable design for obtaining double resonance substrates to be used in surface-enhanced Raman spectroscopy is proposed. Tandem truncated nanocones composed of Au-SiO2-Au layers are designed, simulated and fabricated to obtain resonances at laser excitation and Stokes frequencies. Surface-enhanced Raman scattering experiments are conducted to compare the enhancements obtained from double resonance substrates to those obtained from single resonance gold truncated nanocones. The best enhancement factor obtained using the new design is 3.86 x 107. The resultant tandem structures are named after Fairy Chimneys rock formation in Cappadocia, Turkey.

Laser induced periodic surface structuring for surface enhanced raman spectroscopy Özkarslıgil, Zeynep Tuğçe; Bek, Alpan; Department of Physics (2020) In this study, our aim is to fabricate and characterize efficient substrates of surface enhanced Raman spectroscopy (SERS) utilizing the field enhancement due to hot spots made by recently developed method of laser induced periodic surface structuring (LIPSS). LIPSS is a cost-effective technique for rapid processing of almost any materials compared to conventional lithography methods. Coating of a thin silver film on LIPSS applied substrate surface provides to observe the localized surface plasmon effect fo...
A Solution to the Adhesion Problem of Oxide Thin Films on Zinc Selenide Optical Substrates Cosar, M. B.; Aydogdu, G. H.; Batman, H.; Ozhan, A. E. S. (2016-05-13) Zinc selenide optical substrates have high transparency within the 0.5- to 14.0-mu m wavelength range. This makes them an attractive candidate for multiband imaging applications in optical components. In order to minimize reflection loss in visible, near-infrared, and mid-infrared applications, zinc selenide lenses are coated with multi-layered oxide thin films by physical vapor deposition method or ion beam deposition. In this study, a four-layer anti-reflective filter at 1.064 gm and between 3.6 and 4.9 g...
A feasibility study for controlling self-organized production of plasmonic enhancement interfaces for solar cells Borra, Mona Zolfaghari; Gullu, Seda Kayra; Es, Fırat; Demircioğlu, Olgu; Günöven, Mete; Turan, Raşit; Bek, Alpan (Elsevier BV, 2014-11-01) The decoration of metal nanoparticles (MNPs) by the self-organized mechanism of dewetting is utilized as a suitable method for plasmonic interface integration to large area full-scale solar cell (SC) devices. Reflection measurements are performed on both flat and textured silicon (Si) SCs in order to investigate the local plasmonic resonances of the MNPs. The effects of particle size and thickness of silicon nitride (Si3N4)anti-reflection coating layer are investigated by reflection measurements and the shi...
FABRICATION AND CHARACTERIZATION OF SERS SUBSTRATES VIA LASER INDUCED PHOTOCHEMICAL SURFACE ROUGHENING OF SILICON Akbıyık, Alp; Bek, Alpan; Department of Physics (2022-6-10) In this thesis, Surface-Enhanced Raman Spectroscopy (SERS) substrates are fabricated using laser assisted chemical etching of silicon as a surface nanostructuring technique. As a novel method of control over the structuring parameters, the incident laser illumination is spatially modified via a Digital Micromirror Device (DMD) that enable fast and uniform fabrication of complex structures. Onto the photochemically nanostructured silicon surfaces, silver and gold films are deposited by thermal evaporation or...
Direct epoxidation of propylene to propylene oxide on various catalytic systems: A combinatorial micro-reactor study Kalyoncu, Sule; Duzenli, Derya; Önal, Işık; Seubsai, Anusorn; Noon, Daniel; Senkan, Selim (2015-02-10) A combinatorial approach is used to investigate several bimetallic catalytic systems and the promoter effect on these catalysts to develop highly active and selective catalysts for direct epoxidation of propylene to propylene oxide (PO) using molecular oxygen. 2%Cu/5%Ru/c-SiO2 catalyst yielded the highest performance with high propylene conversion and PO selectivity among the bimetallic catalytic systems including silver, ruthenium, manganese and copper metals. On the other hand, the most effective catalyst...
