The invention discloses a synthesizing method of an Sr2MgSi2O7:Eu2+, Dy3+
nanowire with a long
afterglow lighting function. The synthesizing method comprises the steps of dissolving Mg(NO3)2, Sr(NO3)2, Eu(NO3)3 and Dy(NO3)3 into a mixed
solvent of water and
ethanol to prepare
nitrate mixed solution with the total concentration of
metal ions being 0.02-0.05mol / L, then adding Na2SiO3
solid into
nitrate mixed solution to obtain white turbid liquid, adjusting the pH value to be 2-3, then adding
macromolecule template agent, moving into a hydrothermal kettle and sealing, reacting for 2-4h at 150 DEGC-180 DEG C, pouring out reaction solution, naturally cooling the reaction solution to
room temperature, and filtering the reaction solution to obtain a white precipitate, conducting
vacuum drying on the white precipitate for 10-20h at 80 DEG C-110 DEG C, and putting the white precipitate into a
muffle furnace, and
forging under
reducing atmosphere to obtain the MgSr2SiO4:Eu2+, Dy3+
nanowire with long
afterglow lighting function, which is 30-60nm in
diameter and 4mum in length. The synthesizing method has the characteristics of simple process, low
energy consumption, uniform product size, no agglomeration, excellent lighting performance and the like, and provides a new approach for the research of nano long
afterglow materials.
