    • The present invention relates to a phosphor and a luminous element using the same. The present invention provides a phosphor for absorbing a portion of light emitted from a light source and emitting light with a wavelength different from that of the absorbed light. The phosphor comprises a fluorescent material having an alkaline earth metal-germanium metal-sulfur structure that contains Ge and at least one element selected from the group consisting of Sr and Ca and is activated by Eu. The phosphor of the present invention increases a color rendering index (CRI) of a white luminous element for a general lighting apparatus, and a luminous element using the phosphor has an advantage in that it is suitable for a white luminous element backlight which can substitute for a cold cathode fluorescent lamp (CCFL) in medium and large-sized TVs and has higher color reproducibility and higher white uniformity.
    • 荧光体及使用其的发光元件技术领域本发明涉及一种荧光体及使用其的发光元件。 本发明提供了一种用于吸收从光源发射的光的一部分并且发射波长与吸收光不同的波长的荧光体。 荧光体包括含有Ge和选自Sr和Ca中的至少一种元素并被Eu活化的碱土金属 - 锗金属 - 硫结构的荧光材料。 本发明的荧光体增加了普通照明装置的白色发光元件的显色指数(CRI),并且使用该荧光体的发光元件的优点在于其适用于可替代的白色发光元件背光源 中等尺寸电视机中的冷阴极荧光灯(CCFL),具有较高的色彩再现性和较高的白色均匀性。
