Host Materials

About

Host materials for fluorescent and phosphorescent organic light-emitting diodes (OLED) and thermally activated delayed fluorescence (TADF) devices. Maximize your device efficiency by fabricating and testing new devices in a glove box environment. Host materials play a crucial role in the emissive layer in OLEDs. They assist in transporting electrons and holes efficiently and are therefore described as ambipolar. Host materials transfer energy to the light-emitting molecules/dopants and in some cases, a single molecule can serve as both the host and emitter. On top of this they can stabilize the charge carriers to promote longevity as well as efficiency. Host materials can be placed into three categories: Fluorescent Host Materials Phosphorescent Host Materials TADF Host Materials Selecting the correct material type depends on selection the specific requirements of the device, such as color, efficiency, and operational stability.
