Abstract

: TbF

phosphors were prepared by heating pure natural thenardite with TbF

at 900 ℃ for 20 min in air. Their photoluminescence (PL) spectra were observed under vacuum ultraviolet (VUV)-ultra-violet (UV) light excitation at room temperature. We observed two emission series assigned to the electronic transitions from

and

(J = 6

3 and 2) of Tb

in Na

. The excitation spectrum was consisted of (1) strong bands assigned to the 4f

→4f

n-1

5d transitions (186

190 and 218 nm)

(2) the host absorption (163

200 and 240 nm) and (3) weak bands assigned to the forbidden f-f transitions of Tb

. The relative excitation efficiency in VUV light region is increased with increase of TbF

contents in 0.3%~2.0% range

and the relative excitation efficiency of only the host absorption in UV light region is increased with increase of TbF

contents. This preparation method would be useful for creating new phosphors using pure natural minerals that cannot be synthesized artificially as host crystals.
