The invention relates to a luminescent material of general formula Lny/3Nax-y(AlxSi192-xO384)(MO3)z wherein 0 < x < 96, 0 < y < 96, y < x and z < 20, and Ln comprises one or more elements chosen from the group formed by Sc, Y, La and the Lanthanides and wherein M comprises one or more elements chosen from the group formed by Mo, W, V, Nb and Ta. Luminescent materials of this general formula are relatively cheap and are very suitable for use in low pressure mercury discharge lamps of the three band type.
