Abstract

Abstract: Organic photonic materials have high refractive index, fast transfer speed, low heat generation, and so on; and therefore, have great potential in optoelectronics and optical micro/nanocircuits. Herein, a new strategy using fluorescence–phosphorescence dual emission and disparity of optical loss in a smooth needle‐like organic crystal is reported to realize color tuning of the optical waveguide (OWG). Especially, a warm white‐light OWG emission is achieved by appropriately adjusting the excitation position, presenting the first report of single‐component organic waveguide with white light emission. Based on this, the as‐prepared 1D organic crystal has been demonstrated as a microscale optical correspondence device with multiple input and output responses, which offers potential applications in modern optics and photonics fields. Abstract : The designed single‐component organic needle‐like crystal propagates light at both tips under ultraviolet laser irradiation, when applied to the current prosperous optical waveguide (OWG) application. Due to the loss difference of fluorescence–phosphorescence during light propagation in the crystal, spatially resolved OWG light is obtained with multi‐color and warm white light attributes.
