There is provided a photoactive composition including: (a) 50-99 wt % based on the total weight of the photoactive composition, of at least one host material having a HOMO energy level; (b) 1-10 wt % based on the total weight of the photoactive composition, of an emissive dopant; and (c) 0.1 to 10 wt % based on the total weight of the photoactive composition, of a non-emissive dopant. The non-emissive dopant is an organometallic iridium complex that has a HOMO energy level shallower than the HOMO energy level of the host.
