The YBCO precurcor oxide-water sol adulterated with Au clusters was successively prepared by pulsed laser ablation at the interface of Au target submerged in flowing YBCO precurcor oxide-water sol, YBCO precurcor oxide-water sol with Au clusters dopant was first obtained, then YBCO hybrid materials were obtained after calcination in air. The sol was characterized by TEM and the hybrid materials were characterized by XRD and SEM with an EDX analysis. The TEM and XRD results show that the size of YBCO hybrid materials doped with Au clusters is smaller and its crystallization degree is obviously reduced. EDX analysis indicates that there’s no evidence showing the deviation of Y, Ba and Cu in the YBCO hybrid materials, but Au clusters are detected only in a few regions, which indicates that Au clusters may agglomerate during high temperature calcination.
