The development of new fluorescent nanomaterials is a promising research topic in the field of inorganic chemistry. In this study, spherical Y2O3 nanoparticles doped with europium and terbium ions were successfully prepared using a facile hydrothermal method. Morphology and structural properties of prepared samples were accessed using a range of characterization techniques. PL spectroscopy reveals that the emission spectra of prepared samples consist of several f-f transitions within the doped Tb3+ and Eu3+. As the main aim of this study, we investigated the energy transfer mechanism between the Tb and Eu activators. The observed energy transfer mechanism can be successfully utilized for solid-state white light emitting devices.
