An outlook of rare-earth activated persistent luminescence mechanisms韩少春,王育华,曾巍,陈文波Key Laboratory for Special Function Materials and Structure Design of the Ministry of Education, School of Physical Science and Technology, Lanzhou University摘 要:By studying energy transfer and persistent energy transfer properties in Eu, Mn co-doped calcium aluminate......
that the Tb0.36Dy0.64(Fe1-xMnx)1.9 alloys are composed of MgCu2-type Laves phase as matrix and a small amount of rare-earth rich phase. It is found that the distribution of the rare-earth rich phase has an important.... However, the rare-earth rich phase is arranged as parallel arrays in the directionally solidified samples, which leads to smaller compressive strengths. Key words: magnetostriction; Laves phase; rare-earth......
