    • An array of surface-enhanced Raman scattering substrates based on plasmonic lenses 

      Kahraman, M.; Cakmakyapan, S.; Özbay, Ekmel; Culha, M. (Wiley, 2012-10-01)
      An array of ring-shaped holes is prepared from silver thin films using electron beam lithography. The optimal conditions for high performance as a surface-enhanced Raman scattering (SERS) substrate are investigated. Either ...
    • Cyclodextrin functionalized nanofibers via electrospinning 

      Çelebioğlu, Aslı (Bilkent University, 2014)
      Electrospinning is a commonly studied and widely applied technique for generating nanofibers, with a diameter ranging from several tens of nanometers to a few micrometers. The low-cost, simple set-up, relatively high ...
    • Eco-friendly fabrication of plasmonically active substrates based on end-grafted poly(ethylene glycol) layers 

      Karabel Öcal, S.; Pekdemir, S.; Serhatlıoğlu, Murat; İpekçi, H. H.; Şahmetlioğlu, E.; Narin, İ.; Duman, F.; Elbüken, Çağlar; Demirel, G.; Önses, Mustafa Serdar (American Chemical Society, 2019)
      We report completely sustainable processes and materials for inexpensive and scalable fabrication of plasmonically active solid substrates, which are critical for emerging applications in sensing, catalysis, and metasurfaces. ...
    • Novel materials and techniques for energy conversion and sensing 

      Ekiz, Okan Öner (Bilkent University, 2015-12)
      In the recent years, characterization of nanomaterials and using them in sensing applications gain considerable attention. Increased research on nanotechnology brings new materials and techniques that come with many ...
    • Plasmonic absorbers for multispectral and broadband absorption 

      Ayaş, Sencer; Güner, Hasan; Türker, Burak; Ekiz, Öner; Dana, Aykutlu (SPIE, 2012)
      We present polarization dependent multispectral and broadband plasmonic absorbers in the visible spectrum. The spectral characteristics of these structures are tunable over a broad spectrum. Experimental results are verified ...
    • Plasmonic band gap cavities 

      Kocabaş, Aşkın (Bilkent University, 2008)
      Surface plasmon polaritons (SPP’s) are trapped electromagnetic waves coupled to free electrons in metals that propagate at the metal-dielectric interfaces. Due to their surface confinement and potential in sub-wavelength ...
    • Tunable plasmonic silver nanodomes for surface-enhanced raman scattering 

      Kahraman, M.; Ozbay, A.; Yuksel, H.; Solmaz, R.; Demir, B.; Caglayan, H. (Springer, 2018)
      Surface-enhanced Raman scattering (SERS) is an emerging analytical method used in biological and non-biological structure characterization. Since the nanostructure plasmonic properties is a significant factor for SERS ...
