    摘要: An oxynitride phosphor and a method of manufacturing the same are revealed. The formula of the oxynitride phosphor is Ba3-x-ySi6O12N2:Cey, Eux (0≦x≦1, 0≦y≦1). Europium (Eu) and cerium (Ce) are luminescent centers. The oxynitride phosphor is synthesized by solid-state reaction. The oxynitride phosphor is excited by vacuum ultraviolet light with a wavelength range of 130 nm to 300 nm or ultraviolet to visible light with a wavelength range of 350 nm to 550 nm. The emission wavelength of the oxynitride phosphor is ranging from 400 nm to 700 nm. Thus the oxynitride phosphor can be applied to plasma display panels and ultraviolet (UV) excitation sources. The energy transfer occurs between Ce and Eu of the oxynitride phosphor and the oxynitride phosphor has a blue light emission peak and a green light emission peak. Thus color rendering index of the oxynitride phosphor is improved.

    摘要: A light emitting apparatus includes a blue light emitting diode (LED), a first and second phosphor layers. The second phosphor layer is between the blue LED and the first phosphor layer. When a blue beam of a shorter wavelength excites the phosphor layers, the excitation efficiency of the first phosphor layer is greater than that of the second phosphor layer. When a blue beam of a longer wavelength excites the phosphor layers, the excitation efficiency of the first phosphor layer is less than that of the second phosphor layer. Moreover, the wavelength of the peak intensity of the light beam from the first phosphor layer is shorter than that of the second phosphor layer. And, the dividing value between the shorter wavelength and the longer wavelength is within the range from a first wavelength to a second wavelength.

    摘要: The present invention describes an apparatus and method for manufacturing a white light-emitting diode (LED) using a powder with characteristics of fluorescence to achieve a high-luminosity white LED. The LED emitting ultraviolet light is used as an excitation source, which excites a first powder with blue-green light, and a second powder with orange light. After that, a white light is produced by blending blue-green and orange light with the principle of complementary colors. For achieving the high-luminosity white LED, the invention adopts a suitable LED to be the excitation source with a suitable blending proportion. On the other hand, the implementation of the fluorescent powder with blue-green light can be modulated using a metal ion in the host lattice to change the ligard field of the crystal.

    摘要: A method for manufacturing white light source includes the steps of providing an ultra-violet light as radiation source; and preparing two kinds of phosphors each receiving the ultra-violet light and emitting light of different wavelength. One phosphor is designated to emit light covering two wavelength regimes of three primitive colors, i.e., red light (585-640 nm), green light (500-570 nm) and blue light (430-490 nm), and another phosphor is designated to emit light covering remaining wavelength regime of the three primitive colors. The phosphors are mixed in predetermined ratio such that the lights of different wavelength are combined to provide a white light.
