Inorganic-organic Composite Fluorescent Substance

The present invention relates to a composite fluorescent substance, comprising an inorganic matrix and an organic fluorescent dye, wherein the inorganic matrix is constructed of an inorganic compound selected from the group of metal oxides, metal hydroxides, metal oxide hydroxides, metal phosphates, metal oxide phosphates, metal sulfates, metal oxide sulfates, metal carbonates, metal oxide carbonates, metal silicates, metal oxide silicates, metal borates, metal oxide borates, and mixtures thereof, wherein the inorganic compound comprises one or more each of metal cations that can be the same or different and are selected from Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Sc, Y, La, Ti, Zr, V, Nb, Ta, Zn, B, AI, Ga, In, Ge, Bi, the lanthanoids, and combinations thereof, wherein the organic fluorescent dye comprises one or more functional groups selected from hydroxyl groups, sulfate groups, phosphate groups, phosphonic acid groups, phosphinic acid groups, carboxylate groups, carbonate groups, silicate groups, and borate groups, by means of which the fluorescent dye is installed in the inorganic matrix. The present invention further relates to a method for producing such a composite fluorescent substance and the use thereof.
