Abstract:
Luminescent materials in display devices are desired to have high efficiency, and to be highly resistant to burnout, i.e., to have a long useful life even at high intensities of stimulating radiation. Disclosed is a visual display device which comprises a bismuth-activated material (e.g. 15) which luminesces blue and which is particularly suited for use in high-intensity display devices such as, e.g., cathode ray display tubes.

Abstract:
A fluorescent lamp comprises a glass envelope that is light transmitting. Also included is means for providing a discharge inside the envelope. A discharge-sustaining fill includes mercury and an inert gas sealed inside the envelope. An underlying phosphor- containing layer is disposed inside the envelope. The underlying layer includes zinc silicate phosphor. A protective phosphor-containing layer is disposed over the underlying layer at a location that is more distal from the glass than the underlying layer. A ratio of a surface density of the protective layer to a surface density of the underlying layer is at least 0.4: 1.
