Abstract

In this paper

red afterglow phosphor Y

S ∶ Eu

Gd was prepared by solid state reaction method and the thermal stability was studied in detail. The obtained phosphor compositions were characterized by X-ray diffraction (XRD). Luminescent properties were investigated by measuring emission spectra

excitation spectra and decay curves. When the heating temperature rises from 200 to 600 ℃

the major phase is Y

S and the luminescent properties are almost unchanged. When the heating temperature is 800 ℃

the Y

and Y

phase are observed. The peak position and peak pattern of emission spectrum are unchanged

but the intensity of emission spectrum is decreased. The excitation spectrum shows the same variation regularity. The relative intensity at 5 min (after the excitation source was turn off) is decreased to 80% compared with the one without heating process. When the heating temperature is increased to 1 000 ℃

the major phase is changed to Y

and Y

the intensity of emission spectrum is very low. The afterglow phenomenon almost disappears. The thermal stability of Y

S ∶ Eu

Gd phosphor is better than that of sulfide and aluminates phosphors. Thus

the Y

S ∶ Eu

Gd phosphor is a promising candidate of red afterglow luminescent material which can resistant to higher temperature environment.
