The invention is directed to a composition having a carrier matrix, and a particulate luminescent composition dispersed therein, the particulate luminescent composition comprising a rare-earth-doped alkaline earth fluoride represented by the formula RE.sub.xA.sub.1-xF.sub.2+x-2yO.sub.y wherein RE represents a three-valent rare-earth element, A is alkaline earth, 0.002.ltoreq.x.ltoreq.0.20, and 0.ltoreq.y.ltoreq.x; the particulate luminescent composition exhibiting a luminescence spectrum having a plurality of intensity peaks at characteristic wavelengths. It is further directed to a process by contacting a surface with the composition and articles made therefrom.
