Hydrothermal Synthesis and Luminescence Properties of Eu²⁺- and Eu³⁺-Doped SrAIF₅ Nanorods

J Nanosci Nanotechnol. 2016 Jan;16(1):542-7. doi: 10.1166/jnn.2016.10893.

Abstract

Eu²⁺- and Eu³⁺-doped SrAIF₅ nanorods were synthesized via a hydrothermal process. The crystal structure and morphology of the final products were characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The prepared nanorods' diameters range from 40 to 50 nm, and lengths range from 400 nm to 2 µm along with the doped concentration of rare earth. The f-f transitions of Eu²⁺ can be observed in the SrAlF₅:Eu²⁺ nanorods at room temperature, and the photo-luminescent (PL) properties of SrAlF₅:Eu³⁺ nanorods are also described.
