Photostimulated luminescence of BaBr2 : Eu

Abstract BaFBr : Eu is a well-known photostimulated luminescence (PSL) phosphor used as an X-ray image receptor for digital radiography systems. We fabricated BaBr 2 : Eu and confirmed that it is also a PSL phosphor. An image stored using BaBr 2 : Eu can be read using several different wavelengths; a 780 nm semiconductor laser is particularly attractive because it is very small and high powered.

25.2: Analysis of Deterioration of BaMgAl10O17:Eu2+ Phosphor for Plasma Display Panels

Using TEM, we studied the amorphous phase on a BaMgAl10O17:Eu2+ phosphor surface deteriorated by VUV irradiation. This paper describes growth of the amorphous phase and shows that irradiation from the a-axis of the phosphor crystal intensively increased the growth of the amorphous phase, compared with the results of irradiation from the c-axis.

12.5L: Late-News Paper: High-Luminance 42-in. Full High-Definition PDP

Worlds first 42-inch full high-definition (FHD: 1920×1080) PDP has been developed. It is based on ALIS (Alternate Lighting of Surfaces) method[1] with single scan system. High aperture ratio of 61% is realized by ALIS cell structure and slim barrier ribs with a width of about two thirds of that of HD ALIS (1024×1024). High luminance of 1000 cd/m2 is achieved, and the dark room contrast ratio of 3000:1 is realized by the optimization of drive waveforms.
