Change in the low-voltage luminescence properties of ZnGa{sub 2}O{sub 4}:Mn green phosphors before and after In{sub 2}O{sub 3}-coating was examined by cathodoluminescence. The coating state and distribution of In{sub 2}O{sub 3} nano-particles on phosphors were investigated by field emission scanning electron microscopy (FE-SEM). Especially, based on FE-SEM analysis, the formation of In{sub 2}O{sub 3} nano-particles on ZnGa{sub 2}O{sub 4}:Mn phosphor was confirmed. The improvement of the cathodoluminescence efficiency and lifetime in the In{sub 2}O{sub 3}-coated phosphors was associated with the coating of In{sub 2}O{sub 3} nano-particles.
