Dynamic Duo of Compounds Help LEDs Transmit Wireless Data At High Speed

Today nearly all computers, tablets, and cell phones have Wi-Fi capabilities, receiving and transmitting data over a range of radio frequencies. But a burgeoning technology known as visible light communication could someday carry those data in the same light that illuminates a room using “smart lighting.” Now a tag team of semiconducting organic polymers is bringing that dream one step closer. When excited with a light-emitting diode (LED), the polymer pair helps to create white light that can be rapidly switched on and off to encode information
