1. An organometallic complex with a built-in fluorescent dye having a general formula:

  • ##STR9## where;

    M is a trivalent metal ion;

    O represents oxygen atom;

    L3 is a fluorescent molecule dye;

    L1 and L2 are independently selected from one of the molecules having a general formula I or II or III as shown in the following;

    ##STR10## Where;

    X represents O, NH and CH2 ;

    R1 to R8 represent substitution possibilities at each position and each represent hydrogen or hydrocarbon groups or functional groups selected from cyano, halogen, haloalkyl, haloalkoxy, alkoxyl, amido, amino, sulfonyl, carbonyl, carbonyloxy and oxycarbonyl;

    R10 represents a hydrocarbon group or a functional group such as cyano, halogen, haloalkyl, haloalkoxy, alkoxyl, amido, amino, sulfonyl, carbonyl, carbonyloxy and oxycarbonyl.
