Abstract

We investigated the visible emission property of ultrathin-walled Pb(Zr,Ti)O₃ (PZT) nanotubes (NTs) with various diameters. The PZTNTs were synthesized using the sol-gel templatedirected method with a spin-coating process. The photoluminescence (PL) spectra were measured by using the 325nm photo-excitation as a function of temperature. We observed a sizable green/yellow emission around 550 nm for the PZTNTs at room temperature. With the decreasing temperature, the PL intensity dramatically enhanced, and the peak position shifted to lower energy. We also observed a clear dependence of the PL spectra on the diameter of the NTs. We applied the self-trap exciton model to explain the origin of the emission, and discuss the correlation between the NT geometry and the optical property in the PZT NTs.
