Electronic devices light-emitting diodes

Conjugated organic polymers have been studied extensively over the last twenty years, in part, because of the fundamental and technological interest in their optic and electronic properties. Applications that have been demonstrated for these materials include their use as batteries, sensors, electrochromic devices, light-emitting diodes, and field effect transistors.(i-9) A unique advantage of conjugated polymer materials for these applications is that the properties of the polymer can be... 

One application of modem solid-state electronic devices is semiconductor materials that convert electrical energy into light. These light-emitting diodes (LEDs) are used for visual displays and solid-state lasers. Many indicator lights are LEDs, and diode lasers read compact discs in a CD player. The field of diode lasers is expanding particularly rapidly, driven by such applications as fiber optic telephone transmission.
