Abstract

Abstract : The development of metallic fluorescent materials, π -conjugated molecular systems with high-efficiency generation of blue light, and new ways to fabricate metallic/organic luminescent materials plays an important role in the fields of large-scale flat panel displays and soft optical devices. Herein, different fluorescent films have been fabricated by low vacuum physical vapor deposition method (LVPVDM), including single/two-component films. Compared with raw materials, all films show novel fluorescent behaviors, which means potential application in the fields of multicolor luminescence and thickness-optical response sensors. Meanwhile, the speculation is demonstrated in many ways that the maximum emission (λ e m m a x ) at 406 nm and 426 nm of pristine 2, 6-naphthalenedicarboxylic acid (26NCA) is caused by the crystal structure, while the shoulder peak at 445 nm is caused by the self-structure of 26NCA molecule. Significantly, this speculation may afford new insight into the relationship between not only crystal structure and luminescence, but also molecular self-structure and luminescence, which means a new strategy to tune the fluorescent behaviors based on molecular self-structure by LVPVDM. Therefore, this work provides a facile way to fabricate single/multicomponent metallic/organic film materials with tunable blue luminescence properties, which have potential application in the fields of next generation of photofunctional materials.
