Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a fluorescent material', and more particularly to a soiled aluminate fluorescent material. [Prior Art] In recent years, the improvement of the luminous efficiency of LED chips and the gradual maturity of fluorescent material packaging technology have made the application fields of white LEDs more extensive. In order to pursue higher quality light sources, the industry has adopted short-wavelength UV-LEDs as the development goal, and it is hoped that UV-LEDs and white light of three primary color fluorescent materials will be used as new illumination sources. The white light LED of the three primary color fluorescent materials is excited by UV. The light color is stable and does not shift with the change of current, which can improve the color rendering. Therefore, the use of fluorescent materials of various colors required for white LEDs and the use of colors during light mixing has become the focus of research on fluorescent materials. Among the three primary color fluorescent materials, the luminous efficiency is preferably blue or green. Among them, the alkaline aluminate fluorescent material is a stable and efficient blue and green luminescent material, which has no radioactivity, heat resistance and ring resistance. = Corrosion, good oxidation resistance, etc., also known as green energy-saving materials. In alkaline earth aluminate fluorescent materials, SrA12〇4:Eu2+ is a high-efficiency fluorescent material that can be used to convert visible light. Eu2+ is excited from the ground state to the excited state, and the recovery after the energy level transition produces visible light emission, forming a broadband emission spectrum. For SrAl204:Eu2+ fluorescent materials, the energy level difference caused by the transition of the technology electrons is affected by the ion environment in the crystal field. The crystal field change of the host crystal lattice will cause the difference in the efficiency and color characteristics of the fluorescent material. . On the other hand, the alkaline earth aluminate can also be used as a high-efficiency library long afterglow luminescent material 111986 4 201233781. The rest of the glow is high in brightness and long in duration (more than 12 hours). It can be stored in the daytime and released at night. Light energy has the potential to form a circular illumination mechanism for emergency lighting, low illumination, textiles and accessories. Sr4Al140 25:Eu, Dy is a long afterglow material that can emit blue-green light by UV or visible light. In addition to good afterglow properties, chemical stability and optical stability are quite good and suitable for practical applications. Therefore, there is still a need for an alkaline earth aluminate fluorescent material having high luminance and excellent luminous efficiency. • SUMMARY OF THE INVENTION To achieve the above and other objects, the present invention provides an alkaline earth aluminate fluorescent material having the structure of formula (I): aM, bT cM,, xAl yO : mA, nS ( I ) M ' indicates an alkali gold group element; T system indicates a transition metal element; M" indicates an alkaline earth element; A system indicates a first additive component; S system indicates a second additive component; and a is a number greater than 0, 1). , \, 7, 111, 11 are each independently greater than 0, wherein 0.4Sx / ( a + b + c + m + n ) $ 14.

Comparative Example 1 — (Sr〇.93Mn〇.〇2Eu〇.〇3Bi〇,〇2)4Ali4〇25.04 with (Sr0.89Mn〇.〇2Eu〇.〇5Bi()〇2Li〇.〇2)4Ali4〇25 as solid phase Preparation by law (Sr〇.93Mn〇, 〇2Eu〇.〇3Bi〇.〇2)4Ali4〇25.04 and (Sr〇.89Mn〇.02^11.,G5Bi〇.〇2Li〇.〇2)4Ali4〇25 荣光The body 'according to the chemical composition ratio 'take appropriate amount of SrC〇3, Mn〇2, Eu2〇3, Bi2〇3, Α1·2〇3, LiN〇3 precursor powder. Then, under the reducing atmosphere of nitrogen and hydrogen mixed The crucible® was fired and the calcination temperature was 1300 ° C for 3 hours to obtain (Sr0.93Mn〇.〇2Eu〇.〇3Bi〇.〇2)4Ali4〇25.04 Comparative sample 1 and (Sr〇.89Mn〇. 〇2Eu〇.〇5Bi〇.〇2Li〇.()2)4Ali4〇25 glory powder Sample 5. The fluorescence emission spectra of Comparative Sample 1 and Phosphor Powder Sample 5 are shown in Figure 1. Comparative Sample 1 produced a broad emission peak at a wavelength of 420 nm, and the peak was at 497 nm. After the phosphor powder sample 5 is doped with the valence charge compensator Li+, the fluorescence intensity of the sample 5 is significantly higher than that of the sample 1 compared with φ. [Simplified Schematic] Fig. 1 is a comparison of Comparative Example 1 of the present invention. Fluorescence emission spectrum of sample 1 and phosphor powder sample 5.
