Pyrene-perylene (Py-Pery) doped 2-naphthol (2-NP) luminophors (Py-Pery/2-NP) were prepared by conventional solid state reaction method. Excitation energy transfer and electrical properties were studied by fluorimetry and cyclic voltametric (CV) analysis respectively.2-NP acts as an good light emitting matrix. The effect of the donor emission was perceived by changing the dopant and dopant concentrations; this showed that Py-Pery in 2-NP matrix exhibits green emission in the wavelength region 480-550 nm, peaking at 510 nm. Structural properties and thermal stability was studied by XRD, SEM and TGA-DSC. The HOMO and LUMO energy levels were in the range from 5.46-5.48 eV and 2.76-2.77 eV, respectively. An electrochemical band gap estimated was within the range of 2.68-2.72 eV. This study reveals that 2-NP luminophors can be used as a hole-transporting materials used in optoelectronics.
通过传统的固态反应法制备了芘 - 苝（Py - Pery）掺杂的2 - 萘酚（2 - NP）发光体（Py - Pery/2 - NP）。分别通过荧光光谱法和循环伏安（CV）分析研究了激发能量转移和电学性质。2 - NP作为一种良好的发光基质。通过改变掺杂剂和掺杂剂浓度来观察供体发射的影响；结果表明，2 - NP基质中的Py - Pery在480 - 550 nm波长区域呈现绿色发射，峰值在510 nm。通过XRD、SEM和TGA - DSC研究了结构性质和热稳定性。最高占据分子轨道（HOMO）和最低未占据分子轨道（LUMO）能级分别在5.46 - 5.48 eV和2.76 - 2.77 eV范围内。估计的电化学带隙在2.68 - 2.72 eV范围内。该研究表明，2 - NP发光体可作为用于光电子学的空穴传输材料。
