Paper Title:
Preparation and Properties of Ti, Eu Co-Doped Y2O2S:0.06Ti,0.08Eu Phosphor with Red Long Afterglow
  Abstract

Ti,Eu co-doped Y2O2S:0.06Ti,0.08Eu phosphor with red long afterglow emission from Eu ions was synthesized via traditional sintering method. Results showed that sintering temperature has great influence on the crystal structure, luminescence and afterglow property of the phosphors. The best luminescence and afterglow properties were obtained for the phosphors sintered at 1200°C for 2.5h. Furthermore, only emissions originated from charge transition of Eu3+ was found in the luminescence spectra whereas the afterglow spectra were composed of two sets of emissions: a broad yellow emission band around 565nm and a group of narrow peaks in the wavelength range above 530 nm. The origin of afterglow spectra was discussed: the former is likely related to emission from Ti related traps and the latter is supposed to come from the Eu3+ through an energy transfer process from Ti emission to Eu3+.
