Rapid Synthesis of CaS:Ce~(3+),Sb~(3+) Phosphor with Submicron-scale by Microwave Radiation Method and Its Luminescence

Abstract:

CaS:Ce 3+ ,Sb 3+ phosphors with the green color were firstly synthesized by microwave radiation method. The phosphor materials have been characterized by XRD?SEM and the fluorescent spectroscopy. The result shows that the CaS:Ce 3+ , Sb 3+ phosphors possess the cubic structures. The different shapes and submicro scales of the phosphors can be obtained upon doping the different fluxes in the same concentration of Sb 3+ ion in a microwale field. Ce 3+ can sensitize Sb 3+ , and enhance the fluorescent intensity of CaS:Sb 3+ efficiently.
