Abstract:
A large refractive index difference of 0.58 is demonstrated in organic semiconductor films toward advanced optical design of organic optoelectronic devices. Efficient control of light propagation is shown by distributed Bragg reflectors (DBRs) consisting of organic semiconductor films. The DBRs also show photoconductivity, indicating the promising possibility of active control of both charges and light by the organic semiconductors themselves.
