Preparation of transparent wood containing carbon dots for application in the field of white-LED
Abstract In this study, the biomass carbon dots (CQDs) with blue and yellow fluorescent colors was prepared by citric acid and urea, and two complementary fluorescent molecules, blue and yellow, were used as the donor-acceptor composite system of white fluorescent emission. Transparent wood-based composites which can emit white fluorescence under the excitation of near ultraviolet light were obtained by encapsulating blue and yellow carbon dots in transparent wood. There is no excessive energy transfer between the donor and the acceptor in this material, and the fluorescence intensity can still be kept at 87.7% or above after 7 days of ultraviolet irradiation, and this material has high mechanical strength and good flexibility. These conclusions confirm that the quantum dot/transparent wood-based composite material prepared in this experiment is a promising encapsulating material for white-light emitting diode (W-LED), which has potential application value in the fields of lighting, monitor, intelligent devices and so on.
期刊介绍:
The Journal of Wood Chemistry and Technology (JWCT) is focused on the rapid publication of research advances in the chemistry of bio-based materials and products, including all aspects of wood-based polymers, chemicals, materials, and technology. JWCT provides an international forum for researchers and manufacturers working in wood-based biopolymers and chemicals, synthesis and characterization, as well as the chemistry of biomass conversion and utilization.
JWCT primarily publishes original research papers and communications, and occasionally invited review articles and special issues. Special issues must summarize and analyze state-of-the-art developments within the field of biomass chemistry, or be in tribute to the career of a distinguished researcher. If you wish to suggest a special issue for the Journal, please email the Editor-in-Chief a detailed proposal that includes the topic, a list of potential contributors, and a time-line.
