Abstract

In this study , immersed in a modifier - containing current phase oxides ( europium oxide , zinc oxide , aluminum oxide ) as a solid target , prepared by pulsed laser modified oxides ethanol sol modified oxide / PANI organic sol hybrid films . Using transmission electron microscopy, fluorescence spectroscopy, thermal gravimetric analysis , UV-visible spectroscopy , infrared spectroscopy, four-probe conductivity tests and other methods of preparation conditions on the the modified oxide / polyaniline organosols fluorescence characteristics affect modified oxide nanoparticles structure and modified oxide / polyaniline hybrid films fluorescence characteristics of the conductive nature of its performance . The results show that the modified oxide / polyaniline Organosols , step-by-step preparation of the fluorescence properties than one step better prepared ; under UV irradiation , modified oxide / polyaniline organic sol hybrid films can issue strong fluorescence ; modified oxide / polyaniline conductive properties of hybrid films with respect to the camphorsulfonic acid doped polyaniline film decreased , and improved thermal stability . Pulsed laser were prepared by organic sol green-emitting modified nano - ZnO / polyaniline organic sol and red modification of nano Eu2O3 / polyaniline , mixed according to a certain proportion of modified nano - oxide / polyaniline mixed organic sol its hybrid films . TEM showed that the metal oxide particle size of about 15nm and its high stability in the polyaniline . The hybrid film material to send a strong yellow under UV irradiation . The conductivity of the hybrid thin film material was 0.07 × 10-2 S.cm-1. Thermal analysis shows that the hybrid films film has better thermal stability than the conductive polyaniline ( PAN - HCSA ) .
