SILICON NITRIDE POWDER FOR SILICONITRIDE PHOSPHOR, CaAlSiN3 PHOSPHOR USING SAME, Sr2Si5N8 PHOSPHOR USING SAME, (Sr, Ca)AlSiN3 PHOSPHOR USING SAME, La3Si6N11 PHOSPHOR USING SAME, AND METHODS FOR PRODUCING THE PHOSPHORS |
摘要 |
<p>Provided are: a silicon nitride powder for a siliconitride phosphor with higher luminance, which is used for a fluorescent display tube (VFD), a field emission display (FED), a plasma display panel (PDP), a cathode ray tube (CRT), a light emitting diode (LED) and the like; a CaAlSiN3 phosphor, an Sr2Si5N8 phosphor, an (Sr, Ca)AlSiN3 phosphor and an La3Si6N11 phosphor, each using the silicon nitride powder; and methods for producing the phosphors. The present invention relates to: a silicon nitride powder for a siliconitride phosphor, which is characterized by being a crystalline silicon nitride powder that is used as a starting material for producing a siliconitride phosphor that contains silicon element and nitrogen element but does not contain oxygen element as a constituent element, and which is characterized by having an oxygen content of 0.2-0.9 wt%; a CaAlSiN3 phosphor, an Sr2Si5N8 phosphor, an (Sr, Ca)AlSiN3 phosphor and an La3Si6N11 phosphor, each using the silicon nitride powder; and methods for producing the phosphors.</p> |
