The effect of WO4 group in xerogels doped with Ln2–xPrx(WO4)3 where Ln = La, Gd
photoluminescence praseodymium(III) ions sol–gel method energy transfer process
2011/5/6
We present a synthesis of highly efficient xerogels doped with Ln2–xPrx(WO4)3, where Ln = La
or Gd as novel phosphors. For comparison, the synthesis of xerogels doped only with Pr(III) and
La(III) i...
利用激光剥蚀电感耦合等离子体质谱(LA-ICPMS)微区原位分析方法,对采自西太平洋海山具完整三层结构的富钴结壳样品进行了稀土元素(REE)含量测定,结果表明, 虽然均产于西太平洋海山且均具有明显的三层结构,富钴结壳化学组成受地理位置和沉积环境影响很大。绝大多数西太平洋富钴结壳具有高ΣREE、高LREE/HREE、δCe正异常和δEu基本无异常或微弱正异常的特点, 显示它们主要由正常海水沉积形成。...
