All-Polymer Optoelectronic Devices

摘要

Composites of nanoparticles and conjugated polymers that exhibit composi- tion-tunable optical constants have been developed for use in semiconducting photonic structures. For example, the 550-nanometer wavelength in-plane refractive index of poly(p-phenylenevinylene)-silica composites can be tailored over the range of 1.6 to 2.7, allowing efficient distributed Bragg reflectors and waveguides to be fabricated.
