Abstract
In situ Raman spectra measurements have been employed to reveal the crystallization process of sol-gel derived Bi4-xLaxTi3O12 (BLT) thin films. The Raman spectra of BLT films with a La composition x of 0.75 were measured with increasing temperature up to 800°C in air and N2 ambient. It is demonstrated that Bi2O2 layered structures form first at 500°C and perovskite structures start to crystallize at 600°C or higher.
