Abstract
In the light-emitting layer of a light-emitting device, energy transfer occurs from the host material to the guest material. It not only performs efficiently but also provides a highly reliable light-emitting device. [Solution] In the light-emitting layer of a light-emitting device, the T1 levels of the host material and the guest material, And when the S1 level satisfies a certain range, the transition from the host material to the guest material occurs. Light-emitting devices that can not only efficiently transfer energy but also improve reliability It is a chair.
