Well trap structures and bulk-nano environment luminescence centers in CaZnGe2O6:Tb3+ long afterglow phosphor
A long afterglow phosphor CaZnGe2O6:Tb3+ has been prepared by using organic coated luminescence ZnO nanopowder through a high temperature solid-state reaction route. This new CaZnGe2O6:Tb3+ long afterglow phosphor sample emits the Tb3+ green fluorescence 543 [...]
