| The decorated metal oxide(europium oxide,zinc oxided and alumina)ethanol colloids, decorated metal oxide/(PAN-HCSA) organic collids and the corresponding hybrid films were prepared by pulsed laser ablation at the interface of metal oxide target submerged in flowing liquid containing ligands.TEM,fluorescence spectrum, TG, UV-Vis, FT-IR and Four-Probe Measurement were used to study the influence of experimental conditions on fluorescence properties of the decorated metal oxide/(PAN-HCSA) organic collids, the structure of the decorated metal oxide nanoparticles,fluorescence and conductivity properties of the decorated metal oxide/(PAN-HCSA) hybrid films.It is found that the emission intensity of the decorated metal oxide/(PAN-HCSA) organic collids prepared by stepwise are stronger then one-step preparation. Fluorescence spectrum results showed the organic collids and their hybrid films can emit intense light under ultraviolet radiation.The conductivity of the hybrid films reduced compare to the relate conductive PAN-HCSA film.While TG showed that the hybrid films have better thermo stability than the relate conductive polyanline (PAN-HCSA)film.Decored nano-ZnO/(PAN-HCSA) organic collids and decored nano-Eu2O3/(PAN-HCSA) organic collids were prepared by pulsed laser ablation.Decored nano-oxide mixed organic collids were obtained by mixing the two collids,then the corresponding hybrid films were produced. TEM results showed the diameter of nano metal oxide particles is about 15nm and the nano particles were more stable in PAN.The hybrid films can emit intense yellow light under ultraviolet radiation. The conductivity of the hybrid films was 0.07×10-2S·cm-1. TG showed that the hybrid films have better thermo stability than the relate conductive polyanline (PAN-HCSA)film.
