      Warm white light generating nanocrystal hybridized LEDs with high color rendering index 

      Demir, Hilmi Volkan; Nizamoğlu, Sedat; Zengin, Güliş (IEEE, 2008-11)
      By hybridizing custom-design CdSe/ZnS core-shell NC emitters on InGaN/GaN based blue LEDs, we demonstrated three warm-white light sources with desirably low CCT ranging from 3227 K to 1982 K as is required for SSL indoor ...

      Wavelength dependent color conversion of CdSe/ZnS core/shell nanocrystals for white LEDs 

      Nizamoğlu, Sedat; Demir, Hilmi Volkan (IEEE, 2009)
      Nanocrystals (NCs) provide narrow emission spectrum that can be conveniently tuned using quantum size effect. This ability to adjust and control emission spectrum of NCs makes them strong candidates for use in white color ...

      Nanocrystal hybridized white light sources integrated on near UV leds 

      Nizamoğlu, Sedat; Demir, Hilmi Volkan (World Scientific Publishing, 2007)
      We report on CdSe/ZnS core-shell nanocrystal (NC) based white light sources integrated on near-UV InGaN/GaN light emitting diodes (LEDs). We present the design, epitaxial growth, fabrication, integration and characterization ...

      White CdS nanoluminophore based tunable hybrid light emitting diodes 

      Nizamoğlu, Sedat; Mutlugün, Evren; Akyüz, Özgün; Kosku-Perkgöz, Nihan; Demir, Hilmi Volkan; Liebscher, L.; Sapra, S.; Gaponik, N.; Eychmüller, A. (IEEE, 2007)
      The study aims to fabricate and demonstrate hybrid white light emitting diodes that integrate white emitting CdS nanoluminophores with high light quality. Results show that the white light properties of these hybrid WLED ...

      Nanocrystal integrated light emitting diodes based on radiative and nonradiative energy transfer for the green gap 

      Nizamoğlu, Sedat; Sarı, Emre; Baek J.-H.; Lee I.-H.; Demir, Hilmi Volkan (IEEE, 2009)
      Recently the photometric conditions for ultra-efficient solid-state lighting have been discussed [1-2]. These studies show that a luminous efficacy of optical radiation at 408 lm/Wopt and a color rendering index (CRI) of ...

      Multi-layered CdSe/ZnS/CdSe heteronanocrystals to generate and tune white light 

      Nizamoğlu, Sedat; Mutlugün, Evren; Özel, Tuncay; Demir, Hilmi Volkan; Sapra, S.; Gaponik, N.; Eychmüller, A. (2008-11)
      In this study, tuneable white light generation by controlling CdSe/ZnS/CdSe core/shell/shell heteronanocrystals integrated on InGaN/GaN light emitting diodes was presented. These multilayered quantum dots, also known as ...

      White light generation with CdSe/ZnS core-shell nanocrystals and InGaN/GaN light emitting diodes 

      Nizamoğlu, Sedat; Özel, Sedat; Sarı, Emre; Demir, Hilmi Volkan (IEEE, 2006)
      We present hybrid white light sources that integrate CdSe/ZnS core-shell nanocrystals on blue InGaN/GaN light emitting diodes (LED). We report on the demonstrations of white light generation using yellow nanocrystals ...
