    Study on Preparation of Rare Earth Metal Long Phosphorescence and Its Properties

    • Sol-gel synthesis technique (SST) has been used to prepare SrAl2O4∶Eu2+, Dy3+. The XRD shows that the production prepared at 1 050 ℃ is pure-phase SrAl2O4∶Eu2+, Dy3+, and the phase will not change subjected to the temperature of 1 150 ℃-1 400 ℃. Effects of such factors as the temperature in the sintering process, different proportions of Eu/Sr, different additions of boracic acid, different proportions of Eu/Dy and different proportions of Al/Sr on the relative luminescent height have been studied. The research shows that under the condition of taking hydrogen as reductant, taking 1 200 ℃ as sintering temperature, keeping constant temperature for 2 hours and naturally lowering the temperature, high-quality phosphor products can be produced.
