ABSTRACT:
The luminance of phosphor is enhanced by forming a phosphor screen of a fluorescence generation unit by phosphor expressed by the following composition formula: (L1-a-bGdaCeb)3(Al1-cGac)5O12:Mdwherein, a, b and c are each in the following ranges of 0≦a≦1.0, 0<b≦0.1 and 0≦c≦1.0, M is dopant of a monovalent metal element and is included in phosphor by approximately 0<d≦1000 wt-ppm. Dopant M of a monovalent metal element is at least one type of element selected from a group consisting of K, Na, Li, Cu, Ag and Au. Thus, a display using a white light of improved luminescence and having excellent characteristics can be realized.
