Abstract

A multicomponent equiatomic perovskite - lead strontium calcium titanate (PSCT) was synthesized by reverse co-precipitation with different concentrations of de-ionized (DI) water and ethylene glycol (EG) as a solvent. Structural and optical properties were examined and the phases present in the obtained powder were determined using X-ray diffraction (XRD). The size and morphology were studied by scanning electron microscopy (SEM). Energy dispersive spectroscopy (EDS) was done to confirm near-equimolarity and homogenous distribution of the elements. Thermogravimetric analysis and differential scanning calorimetry (TG-DSC) was carried out to determine the phase changes in the sample. The effect of different proportions of solvent on the calcining temperature and time was studied. Characterisation of the bonds by vibrational analysis was carried out using Fourier - transform infrared spectroscopy (FTIR) and Raman spectroscopy. The indirect bandgap of the sample was determined by diffuse reflectance spectroscopy (DRS) to be 2.67 eV while the direct bandgap was 2.82 eV.

反向共沉淀法制备多组分等原子铅锶钛酸钙(Pb Sr Ca) tio3

以不同浓度的去离子水(DI)和乙二醇(EG)为溶剂，采用反相共沉淀法合成了多组分等原子钙钛矿-铅锶钛酸钙(PSCT)。用x射线衍射(XRD)测定了所制粉末的结构和光学性能。用扫描电子显微镜(SEM)对其尺寸和形貌进行了研究。利用能谱分析(EDS)证实了元素的近等模性和均匀分布。采用热重分析和差示扫描量热法(TG-DSC)测定样品的相变化。研究了不同溶剂配比对煅烧温度和时间的影响。利用傅里叶变换红外光谱(FTIR)和拉曼光谱(Raman spectroscopy)对这些键进行了振动分析。漫反射光谱(DRS)测定样品的间接带隙为2.67 eV，直接带隙为2.82 eV。
