In-situ devitrification of metallo-organic decomposition solutions in the high voltage electron microscope

The decomposition of metallo-organic compound films to yield ceramic oxides with a composition in the lead lanthanum zirconium titanate (PLZT) phase field has been observed using an environmental cell in the transition electron microscope. Diffraction pattern analysis indicates that the first formed phase is lead oxide but that this is rapidly followed by the formation of an homogeneous PLZT composition. The results are supported by differential thermal analysis (DTA)/thermogravimetric analysis (TGA) of the precursor solutions. These observations indicate that it may be practical to prepare thin films of this important electrooptic material by this route.
