Abstract

PURPOSE: To enhance the bluish green luminous efficiency of a Eu(II)-activated alkaline earth metals borophosphate phosphor by replacing part of the alkaline earth metals with specific metals.
CONSTITUTION: Part of the alkaline earth metals of a Eu(II)-activated alkaline earth metals borophosphate phosphor is replaced with one or more of Sc, Y and La to provide a phosphor of a chemical compsn. represented by the formula, where in Me is Sc, Y or La, 0≤x≤0.5, 0≤y≤0.2, 0<z≤0.1, pref. z=about 0.01W0.06, 0.001≤ p≤0.15, pref. 0.005≤p≤0.05, 1.75≤m≤2.30, pref. m=1.9W2.1 and 0.05≤n≤0.23, pref. n=0.14W0.18. This product is excited with cathode rays besides ultraviolet rays of short or long wavelengths and blue visible radiation, and it is suitable for a mercury vapor discharge lamp, a cathode-ray tube, etc.
