Illustration of ABEF film: quantum rods are excited by blue LEDs to give R-G-B light ABEF: Outstanding Display Colors – OLED like colors with LCD • Highly saturated Red, Green and Blue colors are obtained due to the narrow emission bands. • Color gamut increases significantly. Gamut can be tuned to cover NTSC, sRGB and beyond. • Energy saving Regular display With ABEF Optical Switching in single nanorods under electric field -175 Field -350 Electric Electric -175 0 50 m 2.00 2.02 2.04 2.06 m Energy (eV) Switching Eli Rothenberg, Miri Kazes, Ehud Shaviv, Uri Banin, “Electric field induced switching of the fluorescence of single semiconductor quantum rods“, Nano Letters 5, 1581 (2005). “Printed electronics”: Nanocrystal Displays, back lights,LEDs transistors, sensors SiO2 Si Solar energy and environmental: Biomedical apps: passive and Photocatalysis active functions Thank you!
