Green Emitting Phosphor M3(PO4)2∶Ce, Tb (M=Mg, Ca, Sr, Ba) Prepared by Co-Precipitation Method董丽敏,张耀明,韩志东,吴泽,张显友摘 要:The M3-3x(PO4)2∶2xCe, xTb(M=Mg, Ca, Sr, Ba) phosphors were prepared by coprecipitation in this paper. Their phase structures, morphologies and luminescent properties were investigated by X-ray diffractometer, field emission scanning......
simulation method is used to solve free-surface slurry flow problems that may be encountered in several scientific and engineering fields. The main idea behind the use of the particle simulation method..., the movement of each particle is accurately described in the particle simulation method so that the free surface of a slurry flow problem can be automatically obtained. The major advantage of using the particle......
