PHOSPHOR AND LIGHT EMISSION APPLIANCE USING PHOSPHOR
An object of the present invention is to provide an inorganic phosphor having fluorescence properties emitting an orange or red light which has a longer wavelength as compared with the cases of conventional sialon phosphors activated with a rare earth. The invention relates to a design of white light-emitting diode rich in a red component and having good color-rendering properties by employing a solid solution crystal phase phosphor which uses as a host crystal an inorganic compound having the same crystal structure as that of a CaSiAlN 3 crystal phase and to which M Element (wherein M Element is one or two or more elements selected from the group consisting of Mn, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) is added as an emission center.
