Light-emitting material, electroluminescent device containing the same and method for poducing the same

摘要

A light-emitting material includes a polymeric skeleton and a dye moiety. The dye moiety links to the polymeric skeleton by chemical bonding, and has an energy gap lower than that of the polymeric skeleton. As such, energy is transferred from the polymeric skeleton to the dye moiety when the light-emitting material is excited, thereby emitting light.
