<p>Eu-doped ZrO2 and Zr1−xCexO2 (x = 0–0.2) nanoparticles were prepared by a hydrothermal method. The photoemission spectra of Zr1−xCexO2:Eu3+ nanocrystalline samples showed the typical emission of Eu3+ ions assigned to 5D0→7F1 (590 nm) and 5D0→7F2 (610 nm) transitions and additional emissions of 5D0→7FJ with higher J. The spectra were measured at two excitation wavelength of 340 nm (indirect) and 467 nm (direct), and the direct excitation emission was less sensitive compared with 340 nm-induced emission. Asymmetry ratio which was measured by indirect excitation was more effective for monitoring a local lattice distortion in CeO2-ZrO2. This is a fundamental knowledge about luminescent spectra for evaluating the nature of catalytic properties.</p>
