Grystal growth and photoluminescence properties of Eu³⁺-doped Y3Al5O12 nanocrystals by high-energy ball milling

摘要

Y₃Al₅O₁₂:Eu³⁺ powders were synthesized by a high-energy ball mill and characterized. The effects of the crystal size on the crystallinity, morphology, structure and luminescence spectra were investigated by X-ray diffraction, field emission-scanning electron microscopy and photoluminescence spectroscopy (PL). Compared to the solid state reaction method, synthesis by high-energy ball milling is simple, easy to carry out, and the raw materials are commercially available.
