摘要:
A first device comprising a first organic light emitting device (OLED) is described. The first OLED includes an anode, a cathode, and an emissive layer disposed between the anode and the cathode. The emissive layer includes a phosphorescent emissive dopant and a host material. The host material includes inorganic nanocrystals where (i) at least 50% of ligands bonded to said nanocrystals are compact ligands, (ii) an average interparticle distance between adjacent nanoparticles is ≦1 nm, or (iii) both. Also described are a method of making the emissive layer and a composition that includes the phosphorescent emissive dopant with the host materials that include the electronically-coupled inorganic nanocrystal host material.
