<p>Disclosed is a phosphor characterized by having an emission peak in a wavelength range from 490 nm to 580 nm when excited by light having a wavelength of 250-500 nm. This phosphor is also characterized by having a composition represented by the following general formula (2). (M<SUB>1-x</SUB>R<SUB>x</SUB>)<SUB>a2</SUB>AlSi<SUB>b2</SUB>O<SUB>c2</SUB>N<SUB>d2</SUB> (2) (In the formula (2), M represents at least one metal element other than Si and Al; R represents a luminescent center element; and x, a2, b2, c2 and d2 satisfy the following relations. 0 < x = 1, 0.93 < a2 < 1.3, 4.0 < b2 < 5.8, 0.6 < c2 < 1, 6 < d2 < 11)</p> |
