The invention provides a niobate-based luminescent
energy storage material with
high energy storage density and a preparation method thereof. The material includes a top
electrode, a deposition medium, a substrate and a bottom
electrode. The preparation method is as follows: raw materials PbO, SrCO 3 、Na 2 CO 3 , Nb 2 o 5 and SiO 2 After
grinding, heating and melting, it is formed into a sheet in a mold, and after heat treatment of controllable
crystallization, a disc
energy storage target is obtained; BeO, BeCl, Nb 2 o 5 and Sm 2 o 3 After being ground, heated and melted, it is formed into a sheet in a mold, and after a controllable
crystallization heat treatment, a disc light-emitting target is obtained; the
energy storage material and the light-emitting material are respectively deposited on the surface of the substrate, and then through the
photoresist process and magnetic Controlled
sputtering, the surface of the substrate is plated with gold to form the top
electrode, the bottom surface of the substrate is plated with aluminum to form the bottom electrode, and a niobate-based luminescent energy
storage material with
high energy storage density is formed.
