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.
