Abstract
In a method of making an organic electroluminescent device, a transfer layer is solution coated on a donor substrate. The transfer layer includes a polymerizable, amorphous matrix with a light emitting material disposed in the matrix. The transfer layer is then selectively patterned on a receptor. The polymerizable, amorphous matrix is then polymerized. Examples of patterning methods include laser thermal transfer or thermal head transfer. The method and associated materials can be used to form, for example, organic electroluminescent devices.
