Eu3+ doped luminescent nano–materials have become a research focus due to their outstanding physical and chemical properties in light–emitting, magnetism, thermology, catalysis and chemical activity etc.. Furthermore, the relationship between crystal structure and energy levels transition of these nano–materials can be easily obtained by measuring the spectra of doped Eu3+. Among luminescence nano–materials, ZrO2 nano–crystal as a potential one has been attracted great attention in its higher refractive, good optical transparency and relatively low phonon energy. By now certain materials doped RE ion in the matrix ZrO2 for ZrO2∶Er3+–Y3+, ZrO2∶Pr3+ and ZrO2∶(Pr3+, Sm3+) etc., and mesoporous ZrO2 nano–crystals doped Eu3+ by hydrothermal way have been reported. In present study, the ZrO2∶Eu3+ nano–crystal was prepared with high purity and uniform composition by ion exchange method using strong OH− as a precipitant. Its composition, morphology and structure were characterized by XRD, TEM, HRTEM and EDS. The experimental results show that it has a tetragonal crystal structure and its average grain size is 5—20 nm after calcined at 800 ℃ . It is found that the microstructure of ZrO2∶Eu3+ changes slightly with the increase of calcining temperature till a small amount of monoclinic phase forms after calcined at higher than 900 ℃. The luminescent properteof Eu3+ in the ZrO2 nano–crystal were measured by 3D emission and excitation spectra. The characteristic emissin bands of 590 nm (5D0 →7F1) and 606 nm (5D0 →7F2) of Eu3+ were observed at an excitation spectrum of λex=394 nm. The luminescent properties of ZrO2∶Eu 3+ are very sensitive to its microstructure change since slight changes in the ZrO2∶Eu 3+ microstructure cause the changes in the shape and intensity of its emission spectra.
