      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 ...

      High-stability, high-efficiency organic monoliths made of oligomer nanoparticles wrapped in organic matrix 

      Soran-Erdem Z.; Erdem, T.; Gungor K.; Pennakalathil, J.; Tuncel, D.; Demir, Hilmi Volkan (American Chemical Society, 2016)
      Oligomer nanoparticles (OL NPs) have been considered unsuitable for solid-state lighting due to their low quantum yields and low temperature stability of their emission. Here, we address these problems by forming highly ...

      Förster resonance energy transfer enhanced color-conversion using colloidal semiconductor quantum dots for solid state lighting 

      Nizamoglu, S.; Demir, Hilmi Volkan (American Institute of Physics, 2009-10-15)
      In this paper, we present Förster resonance energy transfer (FRET)-enhanced color-conversion using colloidal semiconductor quantum dot nanocrystals (NCs) to make reddish-orange light-emitting diodes for use in ultraefficient ...

      Excitonic improvement of colloidal nanocrystals in salt powder matrix for quality lighting and color enrichment 

      Erdem, T.; Soran-Erdem, Z.; Kelestemur, Y.; Gaponik, N.; Demir, Hilmi Volkan (OSA - The Optical Society, 2016)
      Here we report excitonic improvement in color-converting colloidal nanocrystal powders enabled by co-integrating nonpolar greenand red-emitting nanocrystal energy transfer pairs into a single LiCl salt matrix. This leads ...

      Highly luminescent CB[7]-based conjugated polyrotaxanes embedded into crystalline matrices 

      Erdem, T.; Idris, M.; Demir, Hilmi Volkan; Tuncel, D. (Wiley-VCH Verlag, 2017)
      π-Conjugated polymers suffer from low quantum yields (QYs) due to chain–chain interactions. Furthermore, their emission in solid films is significantly quenched due to aggregation leading further decrease in QY. These are ...

      Stable and efficient colour enrichment powders of nonpolar nanocrystals in LiCl 

      Erdem, T.; Soran-Erdem Z.; Sharma, V. K.; Keleştemur, Y.; Adam, M.; Gaponik N.; Demir, Hilmi Volkan (Royal Society of Chemistry, 2015)
      In this work, we propose and develop the inorganic salt encapsulation of semiconductor nanocrystal (NC) dispersion in a nonpolar phase to make a highly stable and highly efficient colour converting powder for colour ...

      Implementation of high-quality warm-white light-emitting diodes by a model-experimental feedback approach using quantum dot-salt mixed crystals 

      Adam, M.; Erdem, T.; Stachowski, G.M.; Soran-Erdem Z.; Lox, J. F. L.; Bauer, C.; Poppe, J.; Demir, Hilmi Volkan; Gaponik N.; Eychmüller A. (American Chemical Society, 2015)
      In this work, a model-experimental feedback approach is developed and applied to fabricate high-quality, warm-white light-emitting diodes based on quantum dots (QDs) as color-conversion materials. Owing to their unique ...
