Abstract

Cr3+ doped AlF3 phosphors were synthesized via a facile solid state reaction method. XRD results showed that the prepared samples are single-phase. In the emission spectrum of AlF3:Cr3+ powders, there is one sharp line emission located at 695 nm, which is arisen from 2E→4A2 transition of Cr3+ in AlF3 lattice. The excitation spectrum of AlF3:Cr3+ powders monitored at 695 nm emission have two excitation bands of 500~600 nm and 380~450 nm. At room temperature, the fluorescence decay of Cr3+ ions in AlF3 have been measured and the fluorescence decay curve have been reported.
