From the evaluation of the infrared and Raman phonons in undoped ceramics we conclude that tetragonal PZT ceramics undergo a low-temperature phase transition to tilted phase revealed in the anomalies of phonon parameters and the appearance of new modes. Doped samples presented similar behaviour. Workplace Institute of Physics Contact Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Year of Publishing 2011
