Influence of Europium Doping Amount on Properties of Antimony Doped Tin Oxide

Abstract

In order to improve the performance of ATO nanometer powder, using $SnCl_4·5H_2O, SbCl_3$ and $Eu_2O_3$ as raw materials, europium doped ATO non-powder was prepared by co-precipitation method. The precursor was examined by differential thermal gravimetric analyzer and the $Eu^{3+}$ doped ATO nano-powder was examined by XRD and SEM to characterize the crystal structure, particle size and morphology. Comparison was carried out on the ATO nano-powder with or without $Eu^{3+}$ doped. The results found that an appropriate $Eu^{3+}$ doping amount can slightly increase the powder resistance, but to reduce the particle size of the powder and the agglomeration of the powder. Comparing with ATO nano-powder, $Eu^{3+}$ doped ATO nano-powder had better performance.
