One of the most exciting developments in the field of CPs in the last five years was the discovery, first reported by the Cambridge, England group [742], that CPs such as, poly(phenylene vinylene) (P(PV)) could be used as the emissive layer in Light Emitting Diodes (LEDs).

Clinical Experience with Light‐Emitting Diode (LED) Photomodulation
Dermatologic Surgery, 2005Light-emitting diode (LED) photomodulation is a novel nonthermal technology used to modulate cellular activity with light.We describe our experience over the last 2 years using 590 nm LED photomodulation within a dermatologic surgery environment.Practical use of nonthermal light energy and emerging applications in 3,500 treatments delivered to 900 ...

Review: Quantum Dot Light-Emitting Diodes.
Chemical Reviews, 2023Quantum dot light-emitting diodes (QD-LEDs) are one of the most promising self-emissive displays in terms of light-emitting efficiency, wavelength tunability, and cost. Future applications using QD-LEDs can cover a range from a wide color gamut and large

[Light-emitting diodes (LED)].
Annales de dermatologie et de venereologie, 2010LED home-use is now widely spread. In dermatology, numerous reports have stated their results for many indications: wound healing process, rejuvenation, acne and, of course, photodynamic therapy. Nevertheless, fluence, pulse duration and color of the LED are so variable as it is difficult to bring well codified results.

Use of a Light Emitting Diode (LED) Array for Bilirubin Phototransformation
2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005The newborn liver has a limited ability to process unconjugated bilirubin. Thus, infants are prone to an accumulation of unconjugated bilirubin, and can develop jaundice (hyperbilirubinemia). Recently, light emitting diodes (LEDs) which operate in the 410 - 490 nm wavelength range (peak at 475 nm) have been developed.
