چکیده انگلیسی
Manganese-doped zinc silicate (Zn2SiO4:Mn) is a kind of phosphor material that has a photo-luminescent (PL) and cathode-luminescent (CL) properties with intensive green light emission at 520Â nm. The particles consisting of SiO2@Zn2SiO4:Mn (SiO2 core-Zn2SiO4:Mn shell) were synthesized via colloidal process and forced precipitation. After drying, the Zn/Mn precipitates were coated on the surface of SiO2 particles. The Zn/Mn precipitates reacted with SiO2 and transformed to Zn2SiO4:Mn by suitable calcination. The microstructure, crystalline phase, and luminescent characteristics of the products were studied. Besides, a CL device consisting of the core-shell powder was characterized.
