Abstract

In this research, new SrMgAl₂SiO₇:Eu²⁺ phosphor was synthesized via sol–gel method. The phase-forming process and sol-gel reactions were studied by thermogravimetric-differential thermal analysis and X-ray diffraction. The luminescent and morphological properties of this nanocrystal pigment have been systematically investigated. The main emission peaks appeared at 421 nm is ascribed to the 4f⁷ → 4f⁶5d¹ transition of Eu²⁺ in the phosphor lattice. Finally, it was found that the crystallite size of the synthesized powder was about 30 nm by using scherrer equation.
