Description
Technical Field
The invention relates to a blue luminescent material, in particular to a blue luminescent material capable of being excited by ultraviolet light and a preparation method thereof.
Background
Since twenty-first century, white light LEDs as a fourth generation illumination source have the characteristics of environmental protection, high efficiency, energy conservation and long service life, and represent the future development direction of the illumination industry. One of the important ways of realizing the white light LED is the combination of the near ultraviolet LED chip and the fluorescent powder capable of exciting the three primary colors, so that the development of the stable and efficient near ultraviolet white light LED fluorescent powder has important significance.
Through long-term continuous exploration, people fully know the mechanism of blue light luminescence of rare earth ions, and realize the blue light luminescence in a plurality of systems and rare earth materials with various forms. The traditional rare earth activated inorganic fluorescent material with high color purity has received extensive attention for application in backlight display and WLED due to the excellent properties, rare earth ions have typical 4f-5d energy level structures, and the obtained band-shaped emission is easier to realize warm white light illumination similar to solar spectrum.
Firstly, ultraviolet excited trichromatic fluorescent powder, most representative is BaMgAl 10 O 17 :Eu 2+ [ Yin Liangjun, jian Xian, etc. ] A carbon-coated BAM: eu 2+ Blue fluorescent powder and preparation method thereof, application number: CN201410608399.1; wang Yi, zhou Qinqin and other Eu 2+ Ion doped high-light-efficiency blue fluorescent powder, and preparation method and application thereof, application number: CN201811352839.6; zhao Shuying, wang Shuhua, etc., a europium-excited calcium chloroborate blue fluorescent powder, application number is CN101985553A; zhang Jia, chen Guibin Ce3+ activated Ca 7 (PO4) 2 (SiO 4 ) 2 Fluorescent powder and preparation method thereof, application number: CN201810123624.0; liang Pan, liu Zhihong and the like for preparing blue fluorescent powder Sr by self-reduction 2 B 5 O 9 Cl:Eu 2+ Is applied for the method of (a), application number: CN201910991254.7. ' s of
However, the excitation wave bands of the fluorescent powder are far away from the near ultraviolet region, and when the existing ultraviolet chip is used for exciting the full spectrum to simulate the sunlight technology, the chip wave bands are mostly concentrated at 400nm-420nm, and the fluorescent powder is mostly composed of blue, green and red fluorescent powder, so that the fluorescent powder is safer, more reliable and environment-friendly, and is beneficial to protecting eyes of people. However, the existing fluorescent powder has low quantum efficiency and poor stability aiming at 410-420 nm, and seriously affects the light efficiency and stability of the LED. And the red and green fluorescent powder excited by 410nm is basically developed and mature, but the research on the blue fluorescent powder excited by 410nm-420nm with three primary colors does not have a good breakthrough, so that the search for the blue fluorescent powder excited by 410nm-420nm is still an urgent task.
Disclosure of Invention
The invention provides a blue luminescent material capable of being excited by ultraviolet light and a preparation method thereof, wherein the blue luminescent material has stable performance and higher luminous intensity, and the material uses Ca 2 B 5 O 9 Cl as base matrix, rare earth ion Eu is utilized 2+ As a luminescence center, through Ba 2+ Ion and Al 3+ Ion introduction to Eu 2+ Is changed in lattice environment to realize luminescenceIs improved; the chemical composition general formula of the blue light luminescent material is Ca 2-x-y Ba x Eu y B 5-z Al z O 9 Cl, wherein x is more than or equal to 0.1 and less than or equal to 0.7,0.01, y is more than or equal to 0.2,0.25 and z is more than or equal to 1.25.
The preparation method of the material comprises the following steps:
(1) Sample weighing: according to the chemical composition formula Ca 2-x-y Ba x Eu y B 5-z Al z O 9 Cl, wherein x is more than or equal to 0.1 and less than or equal to 0.7, y is more than or equal to 0.01 and less than or equal to 0.2,0.25, z is more than or equal to 1.25, and raw materials such as calcium carbonate, boric acid, calcium chloride, barium chloride, aluminum oxide and europium oxide are weighed according to the corresponding stoichiometric ratio;
(2) Mixing: uniformly mixing the weighed raw materials, and grinding for 1-2 hours to obtain a mixture;
(3) Calcining: calcining the mixture obtained in the step (2) at 750-900 ℃ for 6-7 hours;
(4) Naturally cooling, discharging and crushing to obtain the blue light luminescent material excited by the purple light.
Further, in the step (3), the calcination is carried out in sections, wherein the calcination is carried out at 750-850 ℃ for 2-3 hours, and then at 850-900 ℃ for 3-4 hours.
The invention has the beneficial effects that:
the invention adopts the boron oxychloride as a matrix, has stable chemical property, simple preparation and easy mass production. Traditional Ca 2 B 5 O 9 Cl:Eu 2+ The excitation spectrum of the fluorescent powder is rapidly reduced at 400nm, and the excitation effect is poor when a 410nm light source is adopted. We have found through research that this material is produced by incorporating Al 3+ And Ba (beta) 2+ Ion capable of changing Eu 2+ The lattice environment of the ions further enables the excitation spectrum to still have better blue luminescence at 400nm-420 nm. Excitation of Eu with 410nm 2+ Doped Ca 2-x-y Ba x Eu y B 5-z Al z O 9 Cl can observe 420nm-540nm broadband blue light with 456nm as peak position, as shown in figure 1, under excitation of purple light of 410nm, the product obtained in example 1 is prepared under Ca 2 B 5 O 9 Cl：0.14Eu 2+ The fluorescent powder is enhanced by 28% on the basis, and because the broadband is close to a green light area sensitive to human eyes, when the product is used as the fluorescent powder for a lamp, the effect is better than that of a material with a peak value close to ultraviolet.
