摘要

Disclosed is a divalent europium-activated nitride red-type light emitting phosphor substantially represented by general formula (1): (MI_1-xEu_x)MIISiN₃ ... (1).(In formula (1), MI is a alkaline earth metal element and indicates at least one element selected from a group formed from Mg, Ca, Sr, and Ba; MII is a trivalent metal element and indicates at least one element selected from a group formed from Al, Ga, In, Sc, Y, La, Gd, and Lu; and x is a number that satisfies 0.001 ≤ x ≤ 0.10.) The divalent europium-activated nitride red-type light emitting phosphor is characterized by having electric conductivity of 10 ms/cm or less in a supernatant fluid of a solution containing 10 parts by mass pure water per 1 part by mass of the red-type light emitting phosphor.
