Method of Manufacturing a Printable Composition of a Liquid or Gel Suspension of Diodes

摘要

An exemplary printable composition of a liquid or gel suspension of diodes comprises a plurality of diodes, a first solvent and/or a viscosity modifier. An exemplary method of making a liquid or gel suspension of diodes comprises: adding a viscosity modifier to a plurality of diodes in a first solvent; and mixing the plurality of diodes, the first solvent and the viscosity modifier to form the liquid or gel suspension 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.
