Abstract :
In this article, we report a promising type of reconfigurable OLEDs incorporating a thin carrier-blocking layer as the sacrificial fusing layer. In such devices, the carrier-blocking layer has lower glass transition temperature than neighboring layers. By raising the internal temperature of the device above the transition temperature of the carrier-blocking layer, interdiffusion between organic layers could occur through such layer. As a consequence, neighboring layers are fused and a new path for carrier transport is formed, bypassing the carrier-blocking property and altering the device characteristics. A device that emits blue light as fabricated but can be transformed into a green-emitting one is demonstrated. Such type of devices may be used for color pixels in OLED displays, user-programmable OLED applications, and nonvolatile memory devices.
