Chapter 3 - Evolution of Luminescent Materials for Organic Light-Emitting Diodes

Abstract

This chapter briefly discusses the landmarks in the history of luminescence and covers the prior state-of-the-art on red, green, blue (RGB), and white organic luminescent materials for organic light-emitting devices, displays, and solid-state lighting. Emissive materials with different colors (RGB and white light) have been developed using small organic molecules, polymers, and a variety of dyes as hosts. There has been a constant endeavor to enhance the brightness and efficiency of organic light-emitting diodes by means of using novel organic and polymeric materials to accelerate this green technology for everyday use.
