      Colloidal nanoplatelet/conducting polymer hybrids: excitonic and material properties 

      Guzelturk, B.; Menk, F.; Philipps, K.; Kelestemur Y.; Olutas M.; Zentel, R.; Demir, Hilmi Volkan (American Chemical Society, 2016)
      Here we present the first account of conductive polymer/colloidal nanoplatelet hybrids. For this, we developed DEH-PPV-based polymers with two different anchor groups (sulfide and amine) acting as surfactants for CdSe ...

      Quantum dots on vertically aligned gold nanorod monolayer: plasmon enhanced fluorescence 

      Peng, B.; Li, Z.; Mutlugun, E.; Martinez, P. L. H.; Li, D.; Zhang, Q.; Gao, Y.; Demir, Hilmi Volkan; Xiong, Q. (Royal Society of Chemistry, 2014)
      CTAB-coated Au nanorods were directly self-assembled into a vertically aligned monolayer with highly uniform hot spots through a simple but robust approach. By coupling with CdSe/ZnS quantum dots, a maximum enhancement of ...

      Time-resolved photoluminescence study of CdSe/CdMnS/CdS core/multi-shell nanoplatelets 

      Murphy, J. R.; Delikanli S.; Scrace, T.; Zhang, P.; Norden, T.; Thomay, T.; Cartwright, A. N.; Demir, Hilmi Volkan; Petrou, A. (American Institute of Physics Inc., 2016)
      We used photoluminescence spectroscopy to resolve two emission features in CdSe/CdMnS/CdS and CdSe/CdS core/multi-shell nanoplatelet heterostructures. The photoluminescence from the magnetic sample has a positive circular ...
