文摘

We demonstrate improvements in the electroluminescence switching rate of polymer light-emitting diodes by reducing their active area. We explore the frequency response of devices having a range of sizes and show that LED’s having an active area of 0.02 mm² can be modulated at 16 MHz. The emission from our devices peaks at around 540 nm and thus falls within a transmission window of plastic optical fibers, suggesting possible applications of polymer LED’s as low cost optical communication sources.
