Abstract
Encapsulating luminescent dyes within delignified wood templates is a promising strategy for developing wood-based composite luminescent materials. However, the interactions between the nanopore structure of delignified wood, the loading efficiency of luminescent dyes, and the resulting luminescent properties of these composites remains unclear. In this study, we developed a series of wood-based luminescent composites using delignified wood templates as a dispersion platform for encapsulating classical organic fluorescent dyes. By extensively exploring the interrelationships among the delignification degree, organic dye loading efficiency, and luminescence properties, we uncovered the influence of delignified wood templates on the luminescent characteristics of wood-based luminescent composites. Furthermore, we demonstrated that the luminescent color could be controlled by encapsulating varying proportions of blue-, green- and red-fluorescent dyes, thus enabling the achievement of full-color fluorescence in wood-based luminescent composites. These wood-based luminescent composites hold great promise for applications in data anti-counterfeiting and light-emitting diode technology, offering valuable theoretical support for the development and utilization of innovative wood-based luminescent composites.
