At present, light transmission, energy saving, environmental protection, and UV-shielding materials are very important for optimizing indoor living environment. Here, a fluorescent transparent wood (FTW) with UV-shielding function was prepared by encapsulating a carbon quantum dot and epoxy resin into a delignification wood template. FTW exhibits excellent optical transmittance (about 91%), water absorption stability (weight gain rate less than 9%), longitudinal tensile strength (139 MPa), and UV-shielding properties. Due to the photoluminescence characteristics of the carbon quantum dot and the natural cellulose skeleton of wood, FTW can show uniform luminescence under ultraviolet lamps. At the same time, it has remarkable UV-shielding performance. This kind of photoluminescent transparent wood with a UV-shielding function also has the potential to be applied to fields such as electromagnetic shielding and harmful gas detection.
目前，透光、节能、环保和防紫外线材料对于优化室内生活环境非常重要。在此，通过将碳量子点和环氧树脂封装到脱木质素木材模板中制备了具有防紫外线功能的荧光透明木材（FTW）。FTW表现出优异的光学透过率（约91%）、吸水稳定性（重量增加率小于9%）、纵向拉伸强度（139MPa）和防紫外线性能。由于碳量子点的光致发光特性和木材的天然纤维素骨架，FTW在紫外灯下可呈现均匀发光。同时，它具有卓越的防紫外线性能。这种具有防紫外线功能的光致发光透明木材在电磁屏蔽和有害气体检测等领域也具有应用潜力。
