Abstract

Long afterglow phosphor Y₂O₂S:Gd,Eu,Ti,Mg was synthesized by a gas absorption method and the effect of Ti⁴⁺ and Mg²⁺ ions doping on the luminescent properties was also investigated. Single phase Y₂O₂S can be obtained by calcining the oxide mixture in a graphite crucible absorbed with sulfur. Ti⁴⁺ and Mg²⁺ ions decrease the luminescent intensity of the phosphor, but either Ti⁴⁺ or Mg²⁺ ion doping results in red long afterglow. A strong thermoluminescence peak appears when codoping Ti ⁴⁺ and Mg²⁺ ions in the phosphor.
