Luminescent transparent wood from balsa wood loaded by graphite carbon nitride for application in photoelectric device

In this study, metal-free wood-based encapsulating materials for white light-emitting diode were obtained by using renewable transparent wood as the biological support and the light scattering component, and graphite carbon nitride as the color light emitting component. The graphite phase carbon nitrides with blue and green color were prepared by thermal polymerization through structural regulation of raw materials. The resulting different color phosphors were mixed with epoxy resin, respectively, and then, blue epoxy resin, green epoxy resin and red epoxy resin were mixed with a mass ratio of 4:2:1 and a proper amount of curing agent. The delignified balsa wood with high porosity was vacuum impregnated with epoxy resin mixture to obtain white luminescent transparent wood with better performance such as high transmittance and high haze. This work provides a feasible solution for the sustainable development of transparent wood and the application of transparent wood to photoelectric materials.
