HRTEM investigation of PZT-C-60 thin films

Lead zirconate titanate (PZT, Zr/Ti = 52:46) thin films with added C-60 wer e prepared by firing at 400 degreesC in air. The films were then examined b y high resolution transmission electron microscopy (HRTEM). Analysis of the lattice constants and HRTEM images suggested that C-60 precipitates retain ed in the films were polymerised. Perovskite PZT crystals were observed in contact with the C-60 precipitates, indicating that he C60 precipitates act ed as nucleation sites for the pervoskite phase of PZT.
