摘要： The present invention discloses a low voltage electron excited white lighting device, which comprises a low voltage exciting source and at least two fluorescent substances exhibiting yellow and blue luminous colors after excited by the low voltage exciting source. The host lattice of at least two fluorescent substances is composed of alkaline earth metal and aluminium oxide, and the host lattice is further doped with activator. Furthermore, the fluorescent substance(s) exhibiting yellow luminous color is (Y3-xCex)Al5O12 (0.0001×0.5), and the one(s) exhibiting blue luminous color is (Ba1-xEux)MgAl10O17 (0.0001×0.5). By mixing generated yellow and blue lights, white light is then obtained. Besides, (Y3-xCex)Al5O12 (0.0001×0.5) further absorbs a part of the blue ray emitted from (Ba1-xEux)MgAl10O17 (0.0001×0.5), to thereby emit yellow ray, such that more stronger white light can be obtained. This invention has advantages of forming saturated colors, high reliability, etc. Additionally, the provided fluorescent substances with single phase can be fabricated in a variety of methods, such as solid state reaction method, co-precipitation method, gel method and micro emulsion method. To sum up, the fabricating method disclosed in this invention is simple, suitable for high throughput and has economic effects in industries.

摘要： A white light-emitting device comprising a blue-violet or blue LED and a phosphor material capable of emitting a yellow-green to orange-yellow light upon excitation by the light emitted by the LED. The light from the LED and the phosphor material are mixed in an appropriate ratio to produce a white light. The phosphor material has a general formula (YxMyCez)Al5O12, where x+y=3, x, y≠0, 0.5>z>0, and M is selected from the group consisting of Tb, Lu, and Yb, with (YxMy)Al5O12 serving as a host and Ce as an activator. By changing the composition of the metal elements in the host, the crystal field is modulated to thereby alter the energy level of the excited state to which the activator is transferred upon irradiation by a specific wavelength of light, leading to the change in the emitting wavelength of the phosphor material.
