摘要: A manufacturing method for a nanocrystal light emission substance having a nano structure crystal, doped with an activator and cured with ultraviolet light. The nanocrystal light emission substance is synthesized by a liquid phase co-precipitation process. During the liquid phase reaction, an organic acid, such as acrylic acid or methacrylic acid, is added. Alternatively, a high molecular organic acid, such as polyacrylic or polymethacrylic acid, polystyrene, is added after the liquid phase reaction. The resulting substance is then cured with ultraviolet light.

摘要: A fluorescent material is disclosed which is excellent in the intensity of color and brightness and suitable for a FED and a precise CRT. The fluorescent material is prepared by co-activating yttrium oxide fluorescent material activated with europium. The means particle size is 10 nm to 100 nm. To prepare the fluorescent material, basic carbonate activated with europium and zinc is used as a precursor which is then baked. The precursor is prepared by a liquid-phase reaction. Specifically, yttrium nitrate, europium nitrate and zinc acetate are allowed to react in a solution together with sodium carbonate. The prepared precursor is baked by a quick heating and cooling As an alternative to this, the precursor is baked together with flux (phosphate of alkali metal).

摘要: A liquid crystal display capable of expanding a color reproduction range in the case where a cold cathode fluorescent lamp is used as a light source is provided. A green phosphor of the cold cathode fluorescent lamp includes BaMgAl10O17:Eu, Mn. The wavelength range of a green emission spectrum is located on a shorter wavelength side than that in the case where the green phosphor includes LaPO4:Ce, Tb, so the spectral width of the green emission spectrum is narrower. Therefore, an overlap between the wavelength ranges of green display light and red display light is reduced. Moreover, the spectral characteristics of blue display light (blue spectral characteristics) are set so as to satisfy predetermined conditional expressions. An overlap between the wavelength ranges of the green display light and the blue display light is also reduced.
