<P>PROBLEM TO BE SOLVED: To provide a nitride phosphor having improved brightness, while producing byproducts less than conventional nitride phosphors. <P>SOLUTION: The method for producing the nitride phosphor represented by general formula (1): Ln<SB POS="POST">x</SB>Si<SB POS="POST">y</SB>N<SB POS="POST">n</SB>:Z (wherein, Ln is a rare earth element excluding an element used as an activator; Z is an activator; x satisfies 2.7≤x≤3.3; y satisfies 5.4≤y≤6.6; and n satisfies 10≤n≤12), is characterized by preparing raw materials containing elements constituting the nitride phosphor represented by general formula (1), mixing the raw materials with cesium carbonate and/or cesium nitrate, and then firing the obtained mixture. <P>COPYRIGHT: (C)2013,JPO&INPIT |
