Abstract

The invention discloses a luminescent material [Zn(tibc)2]n and a synthetic method. The molecular formula of a monomer is C18H10ZnBr4N8O2; a molecular weight is 755.33g/mol; Htibc is 3,5-didibromosalicylidene-4-amino-1,2,4-triazole schiff base. Analytically pure 3,5-didibromosalicylaldehyde and analytically pure 4-amino-1,2,4-triazole are dissolved in an analytically pure ethanol solution; an obtained first mixture is heated, refluxed and agitated to obtain the ligand Htibc. The dried Htibc and analytically pure zinc acetate are dissolved in analytically pure N,N'-dimethyl formamide; distilled water is added into an obtained second mixture; an obtained third mixture is stood for five days in a drying oven at 90 DEG C. The [Zn(tibc)2]n generates 526.4nm fluorescent light with intensity of 529.7a.u. (astronomical unit) when being irradiated by 450nm incident light, and under an 800V photomultiplier and a 3 times of amplification coefficient, generates stable emergent light which has intensity of 2910a.u. when being put in a 1mol/L of potassium peroxodisulfate solution.
