Patent ID: 8465676

Claim:
A phosphor for a low-voltage electron beam device having a coated deposition layer formed on the phosphor shown by the following chemical formula (1), CaTiO3:Pr,M (where M is at least one element selected from Al, Ga, In, Mg, Zn, Li, Na, K, Gd, Y and La), wherein the coated deposition layer is a plurality of oxide layers layered on a surface of the phosphor, wherein the oxide layers are layered in a sequence of oxide (MO1)-oxide (MO2)-oxide (MO3), or, oxide (MO2)-oxide (MO1)-oxide (MO3), with respect to the surface of the phosphor, wherein the oxide (MO1) is at least one element selected from Gd, Pr, Y, Zn, Ta, and Sr, wherein the oxide (MO2) is at least one element selected from Si, Al, Mo, Sb, and Ce, wherein the oxide (MO3) is at least one element selected from Ti, W, and Zr.
