摘要

基于BiFeO3的材料是目前研究最多的多铁材料之一，因为它们可能在室温下应用。本研究在不同的烧结温度下合成了两组BFO-1和BFO-2，分别在650℃的煅烧温度和750℃和820℃的烧结温度下合成。用XRD对其结构进行了表征。在820℃下烧结的BFO-2具有比BFO-1更好的性能和菱面体结构。除此之外，还强调了使用FTIR和拉曼光谱技术的光谱诊断。

Structural and spectroscopic characterization of bismuth-ferrites

BiFeO3 based materials are currently one of the most studied multiferroics due to their possible applications at room temperature. In this study two sets of BFO are synthesized at different sintering temperatures i.e. BFO-1 and BFO-2, synthesized at a calcination temperature of 650° C and sintering temperature of 750° C and 820° C respectively. The structural characterization is studied using XRD. BFO-2 which is sintered at a temperature of 820° C shows much better properties as well as rhombohedral structure in comparison to the hexagonal counterpart in case of BFO-1. In addition to this the spectroscopic diagnosis using FTIR and Raman spectroscopic techniques are also highlighted here.
