Eu3+ Doped CaWO4—A Potential Red Long Afterglow Phosphor (Springer Link)
Abstract
In this study, a series of Eu3+ doped CaWO4 phosphors were synthesized by the
solid-state reaction method. Red long afterglow was observed after samples
were excited with 254 nm. The main emission peaks were ascribed to the 5D0–7F
_J_ (_J_=0, 1, 2, 3, 4) transitions of Eu3+, and the duration of the optimal
sample could last nearly 40 min in the dark seen with naked eyes. The effect
of the doping concentration of Eu3+ and alkali metal charge compensators (Li,
Na, K) on the luminescent properties of the products were investigated in
detail. The proposed mechanism of this afterglow property is also discussed.
