The invention relates to a rare earth lanthanum and cerium sulfate which can be used as a red paint and a preparation method of the rare earth lanthanum and cerium. The chemical formula of the paint is: AxLayCe1-yS(3+x)/2, wherein, A stands for one of alkali metals lithium, sodium and potassium, x is equal to or bigger tan 0 and is equal to or smaller than 1, and y is equal to or bigger tan 0 and is equal to or smaller than 1. The alkali metal elements are doped into the rare earth lanthanum and cerium sulfate matrix to prepare rare earth sulfide paints in different red color systems through adjusting the doped amount of the alkali metal elements and different proportions of the lanthanum and cerium in high temperature solid-state reaction with mixed sulfate source gas produced by ammonium thiocyanate being heated and melted as reaction gas under the conditions of unoxidizing atmosphere with inert gas being input and the heating temperature of 400 to 1000 DEG C. The structure of a series of rare earth lanthanum and cerium sulfate doped with the alkali metal elements is NaC1type or Th3P4 type of gamma type in single cubic crystal system. The preparation method is safer and more environment protecting, the paint is non-toxic, so that the paint can be used for coloring for plastic, oil paint, coating, rubber, leather, ceramic, ink, paper, cosmetic and construction material like cement.
