      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 ...
