LEDs and Displays

Light emitting diodes are constantly replacing incandescent and fluorescent light bulbs as brighter and more robust light sources with tailored emission spectra. Extensive research in inorganic, and progressively in, organic materials and devices is done for light emitting materials used in room lighting, display technologies and consumer electronics.

For organic materials, research is driven by the low cost of earth-abundant materials. Attempts are focussed on increasing the efficiency and the stability of the devices associated with electrical transport. This remains a core challenge. In addition, high quantum efficiency is sought for and is associated with low power consumption and thermal requirements.

The fluorescence emission, quantum yield and lifetime of materials for LED can be characterised with a variety of products offered by Edinburgh Instruments.
