Novel optical properties of conducting polymer-photochromic polymer systems

The novel optical properties of a composite film of conducting polymer and acrylate polymer containing photochromic azo-substituent have been studied. The formation of holographic surface relief grating (SRG) using two interf ering beams of a low power laser light has been confirmed in the composite systems. An anomalous angular dependence of photoluminescence (PL) from the composite film having SRG on it has also been observed. Two-dimensional we ll-aligned surface relief structure has been realized by subsequent irradia tion of two interfered light beams on the same surface, which has a potenti al for the novel optical and optoelectronic devices such as a photonic band gap devices.
