Description of the invention: [Technical field of invention] The present invention relates to a yellow orange light zinc sulfide fluorescent material doped with an activator and a preparation method thereof, in particular to a zinc sulfide fluorescent material and a preparation method thereof, It is doped with a first activator (for example: manganese dioxide) and a second activator (for example: barium fluoride or barium vapor) in a sulfurized fluorescent material, so that the sulfurized fluorescent material can be mixed. It emits yellow orange light and blue light to form white light. [Prior Art] In general, phosphors are widely used in illuminating materials for lighting devices, image devices, and display devices. The use of a suitable activator doping dopant material is quite common for improving the luminescent properties of fluorescent materials. In fact, 'the use of appropriate materials (such as: transition metal materials (transiti〇n metal) and rare earth materials [rare earth material] for the activation of the doping technology' can change the luminescent wavelength characteristics of the fluorescent material to achieve the adjustment of its luminescent color For the purpose, or to improve other luminescent properties of the fluorescent material, to achieve the purpose of gain luminous efficiency. Φ For example, U.S. Patent No. 4,579,765

The electroluminescence display device contains a zinc sulfide emission layer with rare earth elements and halides thereof and the phosphorus layer reveals that the zinc sulfide layer contains a first activator selected from the group consisting of rare earth elements [eg, pr [镨], Sm [钐] 〕, Eu [铕], steel [Dy], 鈥 [Ho], bait [Er], 铥 [Tm], etc., Μ [Μη], copper [Cu], silver [Ag], magnesium [Mg], aluminum [] and its halides. The first activator is used to determine the color of the emitted light of the luminescent layer. Further, the zinc sulfide light-emitting layer further comprises a second activator selected from the group consisting of nitrogen [N], phosphorus [P], arsenic [As] and bismuth [Sb]. In fact, the second activator is used to increase the brightness of the zinc sulfide light-emitting layer.

However, U.S. Patent No. 4,579,765 does not disclose how the color of the light emitted by the zinc sulfide luminescent layer forms a yellow orange or white light depending on the material selected for the second activator. In addition, the technology of yellow orange fluorescent materials is also disclosed in the technical content of many US patents. For example, U.S. Patent No. 7,579,765, "Orange-emitting phosphors", U.S. Patent No. 7,489,073, Blue to yellow-orange emitting phosphor, and light source having such a phosphor", U.S. Patent No. 6,682,664 ''Orange-yellow emitting phosphor and cathode-ray tube employing the same'; US Patent Publication No. 20090152575; Orange- Yellow silicate phosphor and warm white semiconductor using same 〃, U.S. Patent Publication No. 20090152495, 'High-brightness yellow-orange yellow phosphor for warm white LED eve, US Patent Publication No. 20080290355, Warm white LED and its Phosphor that provides orange-yellow radiation, US Patent Publication No. 20080274029, Orange-emitting phosphor 〃, US Patent Publication No. 20080083906, 'Orange-emitting phosphor', and US Patent Publication No. 2 'Blue to yellow-orange emitting phosphor·, and light source having such a phosphor".
