| الوصف: | A series of Ce ^3+ /Tb ^3+ singly doped and Ce ^3+ , Tb ^3+ co-doped Ca _3 GdNa(PO _4 ) _3 F phosphors were synthesized via high temperature solid-state reaction in a reductive atmosphere. The crystal, luminescence properties, energy transfer mechanism and thermal stability of the samples were investigated in detail. The Ce ^3+ doped phosphors can be excited in the range from 250 to 330 nm. The Ce ^3+ ,Tb ^3+ co-doped phosphors exhibit characteristic emission of Ce ^3+ and Tb ^3+ simultaneously under the excitation of 301 nm. In addition, the energy transfer efficiency from Ce ^3+ to Tb ^3+ reaches as high as 78.6% when the doping amount of Tb ^3+ is 0.20. The mechanism of energy transfer between Ce ^3+ and Tb ^3+ ions is demonstrated to be a dipole−dipole interaction. The luminescence characteristics show that this phosphor can be a platform for modeling a new phosphor and application in the solid-state lighting field. |
