    • AC-driven, color-and brightness-tunable organic light-emitting diodes constructed from an electron only device 

      Zhao, Y.; Chen, R.; Gao, Y.; Leck, K.S.; Yang X.; Liu, S.; Abiyasa, A.P.; Divayana, Y.; Mutlugun, E.; Tan, S.T.; Sun H.; Demir, Hilmi Volkan; Sun X.W. (2013)
      In this paper, a color- and brightness-tunable organic light-emitting diode (OLED) is reported. This OLED was realized by inserting a charge generation layer into an electron only device to form an n-i-p-i-n structure. It ...

    • Anisotropic stimulated emission from aligned CdSe/CdS dot-in-rods 

      Gao, Y.; Ta, V. D.; Zhao, X.; Wang, Y.; Chen, R.; Zhao, Y.; Dang, C.; Sun, X.; Sun, H.; Demir, Hilmi Volkan (IEEE, 2014-10)
      Anisotropic optical properties of CdSe/CdS dot-in-rods loaded in a capillary tube are demonstrated, suggesting nanorods' alignment with a microfluidic approach. Polarized emissions from photoluminescence and whispering ...

    • Multicolor lasing prints 

      Ta V.D.; Yang, S.; Wang, Y.; Gao, Y.; He, T.; Chen, R.; Demir, Hilmi Volkan; Sun H. (American Institute of Physics Inc., 2015)
      This work demonstrates mass production of printable multi-color lasing microarrays based on uniform hemispherical microcavities on a distributed Bragg reflector using inkjet technique. By embedding two different organic ...

    • Reconfigurable Liquid Whispering Gallery Mode Microlasers 

      Yang, S.; Ta, V. D.; Wang, Y.; Chen, R.; He, T.; Demir, Hilmi Volkan; Sun, H. (Nature Publishing Group, 2016)
      Engineering photonic devices from liquid has been emerging as a fascinating research avenue. Reconfigurably tuning liquid optical micro-devices are highly desirable but remain extremely challenging because of the fluidic ...
