      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 ...

      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 ...

      Critical role of CdSe nanoplatelets in color-converting CdSe/ZnS nanocrystals for InGaN/GaN light-emitting diodes 

      Hasanov N.; Sharma, V. K.; Martinez, P. L. H.; Tan S.T.; Demir, Hilmi Volkan (OSA - The Optical Society, 2016)
      Here we report CdSe nanoplatelets that are incorporated into color-converting CdSe/ZnS nanocrystals for InGaN/GaN light-emitting diodes. The critical role of CdSe nanoplatelets as an exciton donor for the color conversion ...

      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 ...

      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 ...

      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 ...

      Superior warm-White light-emitting diodes integrated with quantum dot nanophosphors for high luminous efficacy and color rendering 

      Nizamoğlu, Sedat; Erdem, Talha; Sun, X. W.; Demir, Hilmi Volkan (Optical Society of America, 2011)
      Quantum dot nanophoshor hybridized warm-white LEDs are reported to exhibit high photometric performance of luminous efficacy exceeding 350 lm/Wopt and color rendering index close to 90 at correlated color temperatures <3000 ...

      Warm-White light-Emitting diodes integrated with colloidal quantum dots for high luminous efficacy and color rendering: Reply to comment 

      Nizamoglu, S.; Erdem, T.; Sun X.W.; Demir, Hilmi Volkan (2011)
      The correlated color temperatures and the corresponding color rendering indices calculated using actual experimental data (and not any prediction) in the original Letter [Opt. Lett. 35, 3372 (2010)] are correct. In addition, ...
