Abstract
An exemplary printable composition of a liquid or gel suspension of diodes generally includes a plurality of diodes, a first solvent and/or a viscosity modifier. An exemplary apparatus may include a plurality of diodes; at least a trace amount of a first solvent; and a polymeric or resin film at least partially surrounding each diode of the plurality of diodes. Various exemplary diodes have a lateral dimension between about 10 to 50 microns and about 5 to 25 microns in height. Other embodiments may also include a plurality of substantially chemically inert particles having a range of sizes between about 10 to about 50 microns.
