Abstract

Fluorescent pyrrole nanoparticles were first synthesized through plasma polymerization under atmospheric pressure and room temperature. The spherical polypyrrole nanoparticles with a diameter of 100-200 nm are uniformly distributed. FTIR was used to investigate the structure of atmospheric pressure plasma polymerized polypyrrole nanoparticles (AP-PPy nanoparticles). The result indicates that the nanoparticles keep a better reservation of the pyrrole structure. The effect of power on the optical property of AP-PPy nanoparticles was analysised with UV-Visble absorption and PL spectra. Polarization induced coplanarization of pyrrole and high level of chain stock during the nucleation and growth of nanoparticles. These lead to a better conjugation of chains, and avoid the aggregation quench. Thus polypyrrole nanoparticles exhibit a strong fluorescence emission at the range of 415nm to 450nm with different power. This technology will help to the realization of practical optoelectronic nanodevice applications of fluorescent polymeric nanoparticles.
