| titleOfInvention | Alkaline earth aluminate fluorescence material for cold-cathode fluorescent lamp, and cold-cathode fluorescent lamp |
| abstract | Under UV excitation of 180 to 300 nm, Eu 2+ and Mn 2+ co-activated alkaline earth aluminate phosphors for cold cathode fluorescent lamps with high brightness and low thermal degradation, and high luminous flux, especially when used as backlights for LCDs, etc. To provide a cold-cathode fluorescent lamp which enables image display of a wide range of green color reproduction.n n n When the composition formula of the phosphor is represented by a (P 1-x Eu x ) 0 · (Q 1-y Mn y ) 0 · bAl 2 O 3 , when the ultraviolet rays with a wavelength of 180 to 300 nm are irradiated, light emission in the blue wavelength range is Alkaline earth aluminate phosphors for cold cathode fluorescent lamps that suppress green light with good match with the spectral transmission spectrum of the green filter (where P represents at least one alkaline earth metal element in Ba, Sr and Ca, Q represents at least one divalent metal element of Mg and Zn, and a, b, x and y each represent 0.8 ≦ a ≦ 1.2, 4.5 ≦ b ≦ 5.5, 0.15 ≦ x ≦ 0.25 and 0.22 ≦. A number satisfying y ≦ 0.4) is referred to as a fluorescent film of a cold cathode fluorescent lamp. |
