Abstract
A method of making polymer blend light active particles, comprising the steps of providing a solution comprised of a first organic light active diode material and a second organic light active diode material in a solvent and providing a non-solvent liquid. The method of making polymer blend light active particles also includes the step of adding the solution to the non-solvent liquid to cause a precipitation reaction resulting in multi-layered particles comprising the first and second organic light active diode materials. A method of making a light active electronic device, comprising the steps of providing at least one of organic and inorganic light active particles in a non-solvent liquid; adding a charge transport carrier polymer to the non-solvent liquid to form a fluid carrier/particle mixture; and disposing the mixture between electrodes to form a light active electronic device.
