• High-pressure scheelite-type polymorph of SmCrO₄: synthesis, structural characterization and magnetic properties

  来源： 《JOURNAL OF RARE EARTHS2010年第6期》——Regino Sáez-Puche Mahmoud Gamal Rabie Julio Romero de Paz José-Manuel Gallardo-Amores Esteban Climent Pascual

  High-pressure scheelite-type polymorph of SmCrO4: synthesis, structural characterization and magnetic propertiesRegino Sáez-Puche,Mahmoud Gamal Rabie,Julio Romero de Paz,José-Manuel Gallardo-Amores... scheelite form of SmCrO4 oxide was obtained by heating the zircon-type SmCrO4 oxide at 4 GPa and 803 K. X-ray diffraction revealed that this scheelite SmCrO4 phase crystallized with tetragonal symmetry......

• Luminescence modification of Eu³⁺-activated molybdate phosphor prepared via co-precipitation

  来源： 《Journal of Rare Earths2009年第5期》——赵春雷 胡运生 庄卫东 黄小卫 何涛

  + as sensitizer ion was investigated on the luminescence of CaMoO4:Eu, and it could strengthen the 406 nm absorption of this phosphor. At last, the scheelite CaMoO4:Eu and wolframite ZnMoO4:Eu were selected to compare their host absorption. The result showed that the scheelite molybdate host exhibited stronger UV absorption than wolframite one.关键词:......
