摘要： A blue-emitting phosphor is optimized by controlling mole fractions typically of Mg and Si in Sr3-eMgbSi2cO8d:Eue or by further including an optimal amount of at least one additional component such as Ba or Ca. The resulting phosphor exhibits a higher brightness and a higher color purity upon excitation by ultraviolet light emitted as a result of discharge of xenon gas. The optimized phosphor is incorporated into light emitting devices such as lamps and PDPs, and further into display devices.

摘要： A problem of the present invention is to reduce discharge delay and discharge voltage in an image display device such as a PDP using ultraviolet rays emission generated by the discharge, thereby improving image quality and reducing cost. In order to solve the above problem, according to the present invention, the image display device using the ultraviolet rays emission generated by discharge includes, within a discharge space, a phosphor where a 1/10 afterglow time is 1 ms or more and a light emitting wavelength is in a range of 200 to 460 nm in which light emitting intensity is at the maximum. Under the same condition, the effect of the invention can be improved by making the 1/10 afterglow time 8 ms or more. Further, the effect of the present invention is further effective by making the 1/10 afterglow time 100 ms or more.
