ABSTRACT:
A display (300, 400) includes a face plate (40, 60) having an inner surface, a back plate (44, 64) having an inner surface opposing the inner surface of the face plate (40, 60), an electron source (48, 68) opposing the inner surface of the face plate (40, 60), and a phosphor (49, 72, 70) disposed on the face plate (40, 60). The phosphor (49, 72, 70) includes an electron-excitable UV-emitting material (52, 72) and a UV-excitable light-emitting phosphor (50, 70). The UV-excitable light-emitting phosphor (50, 70) is disposed to receive UV radiation emitted by the electron-excitable UV-emitting material (52, 72). The electron-excitable UV-emitting material (52, 72) includes a sol-gel product formed using sol-gel techniques.
