PHOSPHORESCENT SMALL MOLECULES THAT ARE BONDED TO INORGANIC NANOCRYSTAL HOST FOR ORGANIC LIGHT EMITTING DEVICES AND METHODS OF MAKING THE SAME

摘要

A first device comprising a first organic light emitting device (OLED) is described. The first OLED includes an anode, it cathode and an emissive layer disposed between the anode and the cathode. The emissive layer includes a phosphorescent emissive dopant and a host material, that includes nanocrystals. The phosphorescent emissive dopant is bonded to the host material by a bridge moiety.
