The formation of alternating electron transporting and hole transporting 15 nm lamellae within the active layer of an organic light-emitting diode (OLED) is demonstrated to improve device performance.

Phase diagrams of four binary blends of polyisobutylene (component 1) and deuterated polybutadiene (component 2) were determined using small-angle neutron scattering (SANS). Our study covers N1/N2 ...
