SrAl2O4: Eu2+, Dy3+ phosphors derived from a new sol-gel route
نویسندگان
چکیده
The SrAl2O4: Eu 2þ, Dy3þ phosphor powders were prepared by a new sol–gel method using aluminum isopropoxide and strontium acetate as precursors. The sol–gel process and the structure of the phosphor powders were investigated by means of DSC-TG and XRD. It was found that the single-phase SrAl2O4 was formed at 900 8C, which is 300 8C lower than that required for the conventional solid-state reaction. The particle morphology, photoluminescence and afterglow properties of the phosphors were studied in this article. q 2003 Elsevier Ltd. All rights reserved.

Nanosized strontium aluminate phosphors prepared via a reverse microemulsion route
Nanosized strontium aluminate phosphors co-activated by Eu2+ and Dy3+ were prepared via a novel reverse microemulsion process. This new ynthesis technique lowered the synthesis temperature of SrAl2O4: Eu2+, Dy3+ phosphors to as low as 900 ◦C, and also reduced the particle size o the nanometer scale (around 40 nm). In the microemulsion process, the constituent cations were trapped by numerous na...
متن کاملEffect of Composition and Impurities on the Phosphorescence of Green-Emitting Alkaline Earth Aluminate Phosphor
Recent improvements to SrAl2O4:Eu2+, Dy3+ phosphors have enabled the use of luminescent hosts with a stable crystal structure and high physical and chemical stability, thus overcoming the bottleneck in the applicability of ZnS:Cu phosphors. However, enhancement of afterglow lifetime and brightness in SrAl2O4:Eu2+, Dy3+ phosphors remains a challenging task. Here, we have improved the afterglow c...

simple and economic coating monitoring technology. The light-emitting properties of the novel coating can serve as an indicator layer, which warns when the coating has worn off, replacing or recoating is necessary [7]. When we inspect on coating with a hand-held UV-lamp, the yellowgreen light of SrAl2O4:Eu, Dy3+ will disappear. It means that the functional coating is worn out and that recoating...
متن کاملCorrelation of Structure, Tunable Colors, and Lifetimes of (Sr, Ca, Ba)Al2O4:Eu2+, Dy3+ Phosphors
(Sr, Ca, Ba)Al₂O₄:Eu2+, Dy3+ phosphors were prepared via a high temperature solid-state reaction method. The correlation of phase structure, optical properties and lifetimes of the phosphors are investigated in this work. For the (Sr, Ca)Al₂O₄:Eu2+,Dy3+ phosphors, the different phase formation from monoclinic SrAl₂O₄ phase to hexagonal SrAl₂O₄ phase to monoclinic CaAl₂O₄ phase was observed when...
متن کاملStructural and Luminescent Properties of Eu2+-doped Aluminates Prepared by the Sol-gel Method.
Alkaline earth aluminates with the overall nominal compositions Mg0.5Sr0.5Al2O4 (MSA), Ca0.5Sr0.5Al2O4 (CSA) and Ca0.5Mg0.5Al2O4 (CMA) doped with 0.5 or 1 mol% of Eu2+ ions were obtained by a modified aqueous sol-gel method and annealed in a reductive atmosphere at 900, 1000, 1100 and 1300 °C. The sample compositions and their structures were studied by XRD employing the Rietveld method. Solid ...
