Organic and inorganic light active devices and methods for making the same
First Claim
1. A method for making a light active device, comprising:
- providing a mixture of light active material and a monomer in a first region and a second region;
forming chains of the light active material in the first region;
selectively cross-linking a monomer from a mixture containing the monomer and the light active material causing a concentration of the light active material at the first region and a concentration of the polymer at second region;
wherein the light active material comprises electro statically active microcapsules comprising an OLED material encapsulated within a polymer shell; and
wherein the chains of the electro-statically active microcapsules are formed by application of an electric field to the mixture of the light active material and the monomer.

Abstract
A light active device includes a semiconductor particulate dispersed within a carrier material. A first contact layer is provided so on application of an electric field charge carriers having a polarity are injected into the semiconductor particulate through the carrier material. A second contact layer is provided so on application of the electric field to the second contact layer charge carriers having an opposite polarity are injected into the semiconductor particulate through the carrier material. The semiconductor particulate comprises at least one of an organic and an inorganic semiconductor. The semiconductor particulate may comprise an organic light active particulate. When constructed as a light emitting device, an electric field applied to the semiconductor particulate through the carrier causes charge carriers of opposite polarity to be injected into the semiconductor particulate. The charge carriers combine to form carrier pairs which decay and give off light.
