摘要:
This work concerns the studies of energy transfers between Sm3+ and Eu3+ ions in some phosphates as new luminescent materials emitting in the orange-red color. The choose of ions is based on the possibility of quantum cutting process and the matrices are selected according to the 5d bands position of Sm3+ ion. The Sm3+ and Eu3+ doped YPO4, LaP5O14 and LaP3O9 are synthesized and spectroscopic studies in ultraviolet and vacuum ultraviolet ranges have been achieved. (C) 2010 Elsevier B.V. All rights reserved.
