methods. The XRD indicates that a pure monoclinic SrAl2O4∶Eu2+, Dy3+ was formed at 1200 ℃ and iron impurity up to 296.36×10-4% had no effect on the SrAl2O4∶Eu2+, Dy3+ phase structure. However...Quenching Study on Iron Impurity in Eu2+, Dy3+ Doped Strontium Aluminate Phosphor Prepared by Nano-Coating Process杨雪峰,宁桂玲,刘杰,潘文,林源摘 要:A series of long......
composites were prepared by copper mold casting under the low vacuum with the argon atmosphere, and the raw materials used in preparing the Mg-Cu-Y-Zn alloys were commercially pure materials... stability of sample prepared with commercially pure raw materials is close to that of sample prepared with the high pure raw materials for the BMG Mg65+X(Cu0.66Y0.33)30-XZn5 (X=6). With the increase of Mg......
