摘要

Optoelectronic devices that include a composite film in a multilayered encapsulation stack are provided. Also provided are methods of forming the light reflection-modifying structures, as well as other polymeric device layers, using inkjet printing. The composite films include a first, lower refractive index domain and a second, higher refractive index domain.
