- Аннотация: Nanocomposites consisting of zinc oxide, erbium oxide, and ytterbium oxide nanoparticles havebeen synthesized from alcoholic solutions and thermally annealed in air. The chemical and phase compositions and microstructure of the resultant samples have been studied using X-ray diffraction, X-ray fluorescence analysis, transmission electron microscopy, X-ray microanalysis, and photoluminescence (PL) spectroscopy. The relative Yb3+ PL intensity in PL spectra of ZnO nanocrystals decorated with Yb2O3 nanocrystals has been shown to increase as twice the Yb3+ excitation energy is approached, which points to a cooperative ion excitation mechanism during electron excitation energy transfer from the ZnO host. If both Er3+ and Yb3+ ions are present in the rare-earth (RE) oxide phase, the Yb3+ PL intensity is lower, attesting to a competition between Er3+ and Yb3+ excitation processes during energy transfer from ZnO to the RE ions. The results obtained in this study pave the way to the use of ZnO- and RE-based nanocomposites for making luminescent sources emitting in a wide spectral range.
