Abstract

This tutorial will review the important properties and performance characteristics of devices such as LEDs, photodiodes, transistor-based displays, and lasers. Organic semiconductor based photoconductors are extensively used in xerographic photoreceptors and constitute the first large market for organic semiconductors. Small molecule and conjugated polymer light-emitting diodes are on the verge of large-scale commercialization, with the first products having recently appeared. The past few years have seen impressive strides being made in improving the efficiency and stability of such devices. Luminous efficiencies >40 Lumens/Watt have been attained.
