Abstract

An organic electronic device to emit or receive radiation includes a cathode, a first layer including a salt, a second layer including an active organic material, and an anode. A method to manufacture an organic electronic device to emit or receive radiation includes depositing a cathode, depositing a first layer including a salt adjacent the cathode, depositing a second layer including an active organic material adjacent the first layer, and depositing an anode adjacent the second layer. An organic electronic device for emitting or receiving radiation includes a cathode, a first layer including a salt, a second layer including an active organic material, and an anode, the anode being adapted to transmit a significant portion of the radiation to or from the second layer.

Claims (11)

1. A method of forming an organic electronic device that receives or emits radiation, comprising the steps of:

depositing a cathode;

depositing a first layer adjacent the cathode, wherein the first layer comprises a salt;

depositing, adjacent the first layer, a second layer comprising an active organic material; and

depositing an anode adjacent the second layer, wherein the anode is adapted to receive or emit a significant portion of the radiation.

2. The method of claim 1 wherein the first layer further comprises an organic material.

3. The method of claim 1 wherein the first layer comprises only a salt.

4. The method of claim 3 further comprising exposing the cathode to water or an alcohol.

5. The method of claim 1 wherein the second layer further comprises a salt.

6. The method of claim 1 wherein the first layer is formed during liquid deposition of the second layer.

7. The method of claim 1 wherein the first layer is separately formed prior to the second layer.
