형광체 및 그것을 이용한 발광 장치
摘要：
본발명은종래의β형사이알론형광체보다휘도를향상시킨형광체를제공한다. 본발명에서는제조후의β형사이알론형광체중에 Al, O(산소), Eu를특정농도로함유시킴으로써형광체의휘도가향상된형광체가제공된다. 즉, Si, Al, O, N 및 Eu를함유하는β형사이알론형광체로서, 형광체중의 Al 농도가 0.80질량% 이상 2.25질량% 이하이고, O 농도가 0.36질량% 이상 1.15질량% 이하이고, Eu 농도가 0.40질량% 이상 0.80질량% 이하이며, O 농도에대한 Al 농도의비(Al/O)가 2.0 이상 3.0 이하인것을특징으로하는형광체를제공한다.
摘要（英）：

The present invention provides a phosphor with improved brightness than sialon phosphor between the conventional β-type. According to the present invention contains Al, O (oxygen), the Eu sialon phosphor after the β-type made of a certain concentration is provided by the luminance of the phosphor improved phosphor. I.e., Si, Al, O, N, and as a β-type sialon phosphor containing Eu, and the Al concentration in the phosphor at least 0.80 mass% 2.25 mass%, and O concentration of more than 0.36 mass% to 1.15 mass%, Eu the concentration is less than 0.40 mass%, 0.80 mass%, a ratio (Al / O) of the Al concentration of the O concentration to provide a phosphor, characterized in that not more than 2.0 to 3.0.
