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 E calculated from the CV found 2.88 eV which are in close agreement with efficient energy transfer in prepared organoluminophors.
蒽-四苯并萘（AN-TN）掺杂对三联苯（p-TP）发光体[(TN-AN/p-TP)(D-A)]和聚苯乙烯掺杂 p-TP 发光体的薄膜是通过传统的固相反应和旋涂技术分别以不同的比例制备的。通过荧光法和循环伏安法研究了激发能量转移（EET）。结果表明，TN-AN/p-TP 在晶态和薄膜中均表现出出色的绿色发射，在 475-550nm 处，峰值在 525nm 处。通过 XRD、SEM 和 TGA-DSC 研究了结构特性和热稳定性。通过 CV 获得的 HOMO 和 LUMO 能级分别在 5.82-5.85eV 和 2.94-2.97eV 范围内。从 CV 计算出的 E 值为 2.88eV，与制备的有机发光体中有效的能量转移非常吻合。
