Variable-temperature ultraviolet Raman spectroscopy study of lead zirconate titanate, PbZr1-xTixO3 (PZT), nanotubes of different wall thicknesses ranging from 3 to 80 nm to be presented. PZT nanotubes were grown on a SrTiO3 substrates by collaborators at University of Wisconsin-Madison. The spectra of the PZT thin film were measured for comparison. Raman spectra were measured with ultraviolet excitation (325 nm) over a temperature range of 10 to 800 K. Analysis of temperature dependence of Raman intensities allowed us to determine ferroelectric phase transition temperature as a function of wall thickness, which was found to vary from ~100 to 650 K.
