Abstract

This invention provides a high-luminance silicate fluorescent material powder and a process for producing the same. The silicate fluorescent material powder comprises at least one element, selected from the group consisting of Mg and Zn, and Si and satisfies formula (1). R = 8 (1) wherein R represents b/a 100 where a and b are determined by steps (i) to (iv): (i) for a blank test, the average value (x) and the standard deviation s of signal strength for each of Mg, Zn and Si are measured without placing any silicate fluorescent material in a measuring cell in an analyzer; (ii) a silicate fluorescent material powder is placed in a measuring cell in the analyzer to measure signal strength for each of Mg, Zn and Si of particles contained in the powder; (iii) the number a of particles in which the signal strength of at least one element selected from the group consisting of Mg and Zn is not less than x + 3s, is measured; and (iv) in the above (iii), the number b of particles in which the signal strength of Si is less than x + 3s, is measured.
