文摘
- •
The afterglow of the SrAl14O25:Eu2+, Dy3+ was improved, doped with moderate Er3+.
- •
The structures of phosphors were characterized by XRD, TEM, HRTEM, FT-IR, and XPS.
- •
The luminescence properties of phosphors were systematically analyzed.
- •
The absorption in the visible region was increased with Er3+ doping in moderation.
- •
The enhancing mechanism of Er3+ on the luminescent properties was analyzed.
