焦磷酸锶:铕(Ⅱ)由于具有与重氮感光体光敏区相匹配的发射光谱,近二十年来被广泛用作重氮复印灯用荧光粉。Wanmakev et al和Logas对它的发光性质作了初步的研究,Gremer等确定了Sr_2P_2O_7的结构。焦磷酸锶:铕(Ⅱ)通常是以SrHPO_4、(NH_4)_2HPO4、Eu_2O_3为原料,干法混合后,经高温灼烧制成。文献报导了将H_3PO_4加入含Eu_2O_3的SrCO_3,经复分解反应得含Eu~(3+)的SrHPO_4,再经还原性气氛高温灼烧成Sr_(2-x)P_2O_7∶XEu(Ⅱ)的合成方法。
Strontium pyrophosphate: Europium (II) has been widely used as a phosphor for diazo-copier lamps for nearly two decades due to its emission spectrum matched with that of diazo photoreceptors. Wanmakev et al and Logas made a preliminary study of its luminescent properties, and Gremer et al. Determined the structure of Sr 2 P 2 O 7. Strontium pyrophosphate: Europium (II) is usually prepared by mixing SrHPO_4, (NH_4) _2HPO4 and Eu_2O_3 as raw materials and then dry-mixing, and then firing at high temperature. The literature reports the synthesis of Sr_ (2-x) P_2O_7: XEu (II) by adding H_3PO_4 to SrCO_3 containing Eu_2O_3 and then decomposing Eu_ (3+) with SrHPO_4 and reducing it to high temperature.
