Abstract
A photo-radiation source for the selective polymerization of photo-radiation-curable organic material. In a first embodiment, a first electrode is provided with a second electrode disposed adjacent to the first electrode, and defining a gap therebetween. A photo-radiation emission layer is disposed in the gap. The photo-radiation emission layer includes a charge-transport matrix material and an emissive particulate dispersed within the charge-transport matrix material. The emissive particulate receives electrical energy through the charge-transport matrix material applied as a voltage to the first electrode and the second electrode photo-radiation. The emissive particulate generates photo-radiation in response to the applied voltage. This photo-radiation is effective for the selective polymerization of photo-radiation curable organic material.
