Abstract

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.

含碳点透明木材在白光led领域应用的制备

摘要本研究以柠檬酸和尿素为原料制备了具有蓝色和黄色荧光色的生物质碳点(CQDs)，并以蓝色和黄色两个互补荧光分子作为白色荧光发射的供体-受体复合体系。将蓝色碳点和黄色碳点包埋在透明木材中，制备出在近紫外光激发下能发出白色荧光的透明木基复合材料。该材料的供体和受体之间没有过多的能量转移，紫外线照射7天后荧光强度仍可保持在87.7%以上，该材料具有较高的机械强度和良好的柔韧性。这些结论证实了本实验制备的量子点/透明木基复合材料是一种很有前途的白光发光二极管(W-LED)封装材料，在照明、监控、智能设备等领域具有潜在的应用价值。

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.
