The present invention provides a white light emitting diode for emitting
white light with warmness at a higher luminance, and an intermediate
color light emitting diode satisfying light emission with diversified
color tones at a higher luminance. A fluorescent material which emits
yellowish red or red light and has a CaAlSiN.sub.3 crystal phase
including, dissolved therein in a solid state, one or more element(s)
selected from Mn, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu.
The fluorescent material is mixed with another fluorescent material
emitting green, yellowish green, or yellow light, and the mixed phosphor
is combined with a semiconductor light emitting element for emitting
bluish purple or blue light, to fabricate a white light emitting diode
which efficiently emits a warm white light with a high efficiency.
