摘要： A green light emitting phosphor comprising tetravalent elements added to a green light emitting phosphor, Y.sub.3 (Al,Ga).sub.5 O.sub.12 :Tb, wherein the green light emitting phosphor can prevent a so-called electron beam burning even when excited by electron beams of high energy. The green light emitting phosphor is, particularly suitable to be applied to a projector tube or a high-brightness phosphor display tube.
