Abstract
The number of anthracene-tetracene (AN-TN) doped p-terphenyl (p-TP) luminophors [(TN-AN/ p-TP) (D-A)] and thin films of polystyrene doped p-TP luminophors were prepared at different proportion by conventional technique called solid state reaction and spin coating technique respectively. Excitation energy transfer (EET) was studied by fluorimetry and cyclic voltammetry technique. The result showed that, TN-AN/ p-TP in crystalline state as well as in thin films exhibit outstanding green emission at 475–550 nm, peaking at 525 nm. Structural properties and thermal stability were studied by XRD, SEM and TGA-DSC. The HOMO and LUMO energy levels obtained by CV were in the range from 5.82–5.85 eV and 2.94–2.97 eV, respectively. The Eg calculated from the CV found 2.88 eV which are in close agreement with efficient energy transfer in prepared organoluminophors.
