Preparation of Eu³⁺-Doped Rutile TiO₂ Nanocrystals at Room Temperature by a Sonochemical Method

Abstract:

Lanthanide-doped semiconductors find usage in a wide variety of applications. In this work, Eu³⁺-doped rutile TiO₂ nanocrystals have been successfully prepared at room temperature by a sonochemical method. The nanocrystalline sample has been characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM) techniques. A possible mechanism is proposed to explain the formation of Eu³⁺-doped TiO₂ nanomateirals. Additionally, the characteristic emissions of Eu³⁺ can be found upon excitation in the region of TiO₂ absorption, indicating that an energy transfer from TiO₂ to Eu³⁺ occurs for the doped sample.
