Abstract
In one method of making an organic electroluminescent device, a transfer layer is solution coated on a donor substrate. The transfer layer includes an amorphous, non-polymeric, organic matrix with a light emitting material disposed in the matrix. The transfer layer is then selectively patterned on a receptor. 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.
Claims7
An electroluminescent device, comprising:
- a first electrode;
- a second electrode;
- and
- a light emitting layer disposed between the first and second electrodes, the light emitting layer comprising an amorphous, non-polymeric organic matrix with a light emitting polymer disposed in the matrix.
