Located in media technology_light-generation_world-record-white-oled-performance-exceeds-100-lm-w_doe_oledrek08_sm-jpg Located in media OSRAM has achieved new records in the laboratory for white light – 155 lm for brightness and 136 lm/W for efficacy (at 350mA). Luminus flux and efficacy vs. drive current. Located in media The new technique reduces the number of defects in those films by two to three orders of magnitude -- increasing the output of light by a factor of two for a given amount of power.

(a) The nanospheres are first spin-coated onto the sample, followed by dry etching to define patterns. (b) The silica spheres and protection layer are then removed. The device-fabrication process is completed following deposition of contact metal. (c) Structure of an LED equipped with nanorod reflectors. Located in media Figure 1. Scanning-electronic-microscope image of self-organized silica nanospheres. The diameter is 100nm. Mag: Magnification.
