    • PURPOSE: A blue fluorescent substance, fluorescent lamp including thereof, and a high quality liquid crystal display device which has long lifetime and high color reproduction range are provided to facilitate center emission wavelength and to enhance color purity and stability of heat and moisture. CONSTITUTION: A blue fluorescent substance includes a substance which is represented by chemical formula 2: 2×(a×SrCl2*x'H2O + b×CaCl2*x''H2O + cNH4Cl + d(j'Sr(NO3)2 + k'SrCO3) + e(j''Ca(NO3)2 + k''CaCO3) + f(1/2Eu2O3)) + 5×(g(j'''B(OH)3 + k'''B2O3) + hAl2O3 + h'SiO2). Here, a + b + d + e + f = 1, 0.25 Δ a + b Δ 0.999, 0.1 Δ a + d Δ 0.8, 0 Δ c Δ 6, 0.001 Δ f Δ 0.5, 1 Δ g + h + h 'Δ 1.5, 0.9 Δ g Δ 1.5, j' + k '= 1, j' '+ k' '= 1, j' '' + k''' = 1, 0 Δ x' Δ 10, 0 Δ x'' Δ 10, 0 Δ 2×x' + 2×x'' + 5×g×j''' Δ 50.
    • 目的:提供具有长寿命和高色彩再现范围的蓝色荧光物质及其荧光灯以及高品质的液晶显示装置,以促进中心发射波长并提高色纯度和热和水分的稳定性。 构成:蓝色荧光物质包括由化学式2表示的物质:2×(a×SrCl 2 * x'H 2 O + b×CaCl 2 * x'H 2 O + cNH 4 Cl + d(j'Sr(NO 3)2 + k + 5×(g(j“'B(OH)3 + k”'B 2 O 3)+ e(j'Ca(NO 3)2 + k'CaCO 3)+ f(1 / 2Eu 2 O 3) + hAl2O3 + h'SiO2)。 这里,a + b + d + e + f = 1,0.25△a + b△0.999,0.1△a + d△0.8,0△c△6,0.001△f△0.5,1△g + h + h' Δ1.5,0.9ΔgΔ1.5,j'+ k'= 1,j“+ k”= 1,j“'+ k”'= 1,0Δx'Δ10,0Δx' 'Δ10,0Δ2×x'+ 2×x“+ 5×g×j”'Δ50。
