Crystal-Plane-Dependent Photoluminescence of Pentacene ID Wire and 2D Disk Crystals

摘要

Photoluminescence (PL) is an important optical phenomenon that has been widely studied for the development of light-based applications, including displays, lasers,sensors, and biotags. Traditionally, PL has been studied for ensemble organic and inorganic compounds in solution and solid-state inorganic semiconductors that possess direct band-gap energies corresponding to visible-light wavelengths. Interest has recently moved to the PL activity of low-dimensional inorganic and organic conducting or semiconducting materials toward developing applications in flexible and cost-effective optical and optoelectronic devices PL activity of geometrically well-defined organic molecular and polymeric structures has been of particular interest owing to their recently demonstrated optical-waveguiding and lasing properties.
