ABSTRACT:
A fluorescent composition for low velocity electron beam excitation, comprising a phosphor containing a sulfide of the formula (Zn.sub.1-x,Cd.sub.x)S wherein x is a number satisfying a condition of 0.ltoreq.X.ltoreq.1, as the host material, and an electrically conductive material mixed or mutually adhered to each other, wherein the half value width (2.theta.) of the strongest diffraction line in the diffraction X-ray spectrum of said sulfide is within a range of from 0.05.degree. to 0.16.degree..
