Fluorescent Host Materials
Fluorescent host materials play a critical role in the performance of organic light-emitting diodes (OLEDs), serving as a medium to transfer energy efficiently to the dopant (emissive material). They are considered the first-generation OLED materials and are defined by their fluorescent recombination mechanism. These materials are designed to maximize device efficiency, stability, and color purity while minimizing energy losses.
The key characteristics of fluorescent host materials include:
Wide Energy BandgapHigh Triplet EnergyHigh Ambipolar Charge TransportFluorescent host materials are typically low cost and stable, but aren't as efficient as later generations of OLED materials. First-generation fluorescent emitters can only support radiative emission through singlet-singlet emissions.

Fluorescence and Phosphorescence
Fluorescence and phosphorescence are types of photoluminescence. Photoluminescence refers to radiative emissions where the absorbance of a photon is followed by the emission of a lower energy photon.
