摘要

A series of novel acenaphthene (Acnp) luminophores were prepared by doping varying concentrations of anthracene (AN) and perylene (Pery) by the solid-state reaction method, and studied for their fluorescence characteristics. The prepared Acnp luminophores were excited at the excitation wavelength of the host, Acnp. The fluorescence excitation energy transfer (EET) was observed in these bi- and tri-component luminophores. The complete quenching of weak violet fluorescence of Acnp was noted with the appearance of new AN like emission in bi-component while monomeric emission of Pery in tri-component luminophores. The prepared luminophores were further characterized by X-ray diffraction, TGA, and cyclic voltammetry to study structural parameters, thermal stability, and electrical properties, respectively. The particle size of the prepared luminophores was calculated by scanning electron microscopy (SEM). The present study reveals that the prepared novel Acnp luminophores show two-step EET from the host Acnp to AN and from AN to the second guest Pery in the Acnp matrix. The prepared luminophores could be used in organic light-emitting devices and in optoelectronic devices.
