Several perylene (Pery)-doped 2-naphthol (2-NP) (Pery/2-NP) luminophors were prepared using conventional solid-state reaction techniques. Energy transfer in the excited state was examined using fluorescence spectroscopy and cyclic voltammetry. Fluorescence studies revealed exciplex formation by Pery in the form of structureless and broad spectra at higher concentrations with monomer quenching of 2-NP; a broad green emission was observed in the range 500-650 nm, peaking at 575 nm. Structural properties and thermal stability were analyzed using X-ray diffraction, scanning electron microscopy and TGA-differential scanning calorimetry. Highest occupied molecular orbital and lowest unoccupied molecular orbital energy levels were observed in the range 5.56-5.61 eV and 2.79-2.81 eV, respectively with a 2.77-2.82 eV band gap. The present study reveals these to be probable candidates for hole-transporting materials suitable in optoelectronics.

ylene掺杂的2-萘酚发光体的光物理和结构方面：激基复合物形成的绿色发射。

使用常规的固态反应技术，制备了几种掺有per（Pery）的2-萘酚（2-NP）（Pery / 2-NP）发光体。使用荧光光谱法和循环伏安法检查激发态下的能量转移。荧光研究表明，Pery形成的激基复合物在较高浓度下以2-NP单体猝灭形成无结构和宽光谱的形式。在500-650 nm范围内观察到较宽的绿色发射，在575 nm处达到峰值。使用X射线衍射，扫描电子显微镜和TGA差示扫描量热法分析结构性能和热稳定性。在5.56-5.61 eV和2.79-2.81 eV范围内分别观察到最高的占据分子轨道能级和最低的未占据分子轨道能级，且带隙为2.77-2.82 eV。
