<P>PROBLEM TO BE SOLVED: To provide a red light-emitting phosphor having a luminous efficiency higher than that of the conventional and to provide a high-luminance light-emitting module using the same. <P>SOLUTION: The red light-emitting phosphor is represented by the formula: (M<SB>1-x</SB>, Eu<SB>x</SB>)P<SB>3</SB>O<SB>9</SB>(wherein M is a rare earth metal element; and 0≤x<1), desirably has an excitation peak wavelength of 350 to 420 nm, more desirably 385 to 405 nm. It can constitute a high-luminance light-emitting module when combined with a semiconductor light-emitting element of an emission peak wavelength of 350 to 420 nm. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
