(Color online) (a) Plan-view optical micrograph of an UV microstripe LED array, showing a pattern of one stripe on/three stripes off (not true color). (b) The vertical light emission profile of one of the microstripe LED elements.
(Color online) (a) Schematic diagram and (b) optical micrograph of a polymer microstripe directly “written” on top of an UV microstripe LED.
(Color online) Optical micrograph (not true color) of an operating hybrid inorganic/organic microstripe LED device, showing a turned on bare stripe LED (top), a turned off bare stripe LED (center), and a turned on hybrid stripe LED (bottom).
(Color online) (a) Normalized absorption spectrum (dash dot line) of a poly(9,9-dioctylfluorene) (PFO) film and emission spectrum (solid line) of an UV microstripe LED. (b) Emission spectra of a hybrid microstripe LED (solid line), a PFO film (dash dot line), and of the vinyl ether polymer (short dash line).
