Hilmi Volkan Demir's Research Group achieved solid-state white light generation using nanocrystal hybridization on light emitting diodes, with tunable color properties for the first time in the world. The article "White Light Generation Using CdSe/ZnS Core-Shell Nanocrystals Hybridized with InGaN/GaN Light Emitting Diodes" by Demir's group members Sedat Nizamoğlu, Tuncay Özel, Emre Sarı, and Dr. Hilmi Volkan Demir is highlighted as a featured article on the hard cover of the prestigious journal NANOTECHNOLOGY (vol. 18, no. 6 in the issue of 14 February 2007). NANOTECHNOLOGY is the first journal dedicated to all aspects of the cutting-edge nanoscale science and technology from a multidisciplinary perspective and currently one of the top journals at the forefront of nanoscience and nanotechnology. Asst. Prof. Demir is working at the Department of Physics and the Department of Electrical and Electronics Engineering; his research group and labs are located at the Nanotechnology Research Center and Advanced Research Laboratory.

White LEDs have attracted both scientific attention and commercial interest world wide as one of the next great solid-state frontiers, with their potential wide-scale use in architectural lighting and automotive industry. Unlike prior approaches, the Demir Devices and Sensors Lab generated white light with tunable color properties using multiple combinations of nanocyrstals, each of which features a narrow emission spectrum widely tunable across the visible. This work included the design, modeling, epitaxial growth, fabrication, experimental characterization, and theoretical analysis of their white hybrid nanocrystal-LEDs. These light sources hold great promise for future lighting and display applications with highly adjustable optical properties.
