Characterization and properties of a red and orange Y2O2S-based long afterglow phosphor
TL;DR: In this paper, the effect of various sintering atmospheric conditions on the crystalline phases and luminescent properties of the products were investigated in detail, and red and orange long afterglow was observed after phosphors were excited with 365nm ultraviolet light.

Synthesis of Eu3+-activated yttrium oxysulfide red phosphor by flux fusion method
TL;DR: In this article, the synthesis of the yttrium oxysulfide red phosphor by the flux fusion method was presented, and the effects of flux compositions and sintering conditions on the shape and size distribution of phosphor were studied.
Journal ArticleDOI
Eu3+ red long afterglow in Y2O2S:Ti, Eu phosphor through afterglow energy transfer
TL;DR: In this paper, the afterglow color of Y2O2S:Ti,Eu phosphors was investigated by photoluminescence (PL) spectra and thermolumine spectrum measurements.

Synthesis and characterisation of rare earth oxysulphide phosphors. I. Studies on the preparation of Gd2O2S:Tb phosphor by the flux method
Elisabeth-Jeanne Popovici,Laura Muresan,Amalia Hristea-Simoc,Emil Indrea,Marilena Vasilescu,Mihail Nazarov,Duk Young Jeon +6 more
TL;DR: In this paper, the synthesis of Gd 2 O 2 S:Tb phosphor by solid-state reaction route from oxide precursors was presented. But the results were limited to the use of X-ray intensifying screens for medical diagnosis.

Eu3+ doped yttrium oxysulfide nanocrystals – crystallite size and luminescence transition(s)
TL;DR: Nanocrystals of yttrium oxysulfide doped with trivalent europium have been synthesized using a two-step sol-gel polymer thermolysis method employing urea formaldehyde resin in the presence of ethylene diamine tetra acetic acid as chelating agent as mentioned in this paper.
