Photoluminescent textiles emitted light in ultraviolet (UV)-radiation region has advanced a variety of applications including military and police clothes. The current study reports the preparation of photoluminescent viscose fabrics incorporated lanthanide metal-organic framework (Ln-MOF) and their applications for self-cleaning. In situ growth of Ln (Eu3+, Tb3+) MOF into viscose fabrics were achieved using Ln (NO3)3 and 1,2,4,5-benzenetetracarboxylic dianhydride as organic ligand. The in-growth Ln-MOF within fabrics were characterized using X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscope, energy dispersive X-ray, and fluorescence spectroscopy. Under the UV lamb (345 nm), [email protected] fabric and [email protected] fabric visually emitted red and green color, respectively. The excitation-emission spectra showed the spectra for the 5D07F0-4 transitions and 5D47F5 transitions in case of Eu-MOF and [email protected] fabrics, respectively. The photoluminescent properties of [email protected] fabrics were enhanced after reactive dying process. The self-cleaning functions of [email protected] fabrics were estimated through studying the photo-degradation of Rhodamine B (RhB) dye over the fabrics. After 120 min irradiation time, the photo-degradation of RhB dye was 85–97%, indicating high performance of [email protected] fabric. The materials are promising for advanced applications including protective clothing, textile-based sensors, smart tagging and tickets.

掺镧-有机骨架(Ln-MOF)的自清洁光致发光粘胶织物

光致发光纺织品在紫外线(UV)辐射区域发出光,已在包括军事和警察服装在内的各种应用中取得了进展。当前的研究报道了结合了镧系金属-有机骨架(Ln-MOF)的光致发光粘胶织物的制备及其在自清洁中的应用。使用Ln(NO 33将Ln(Eu 3+,Tb 3+)MOF原位生长为粘胶纤维和1,2,4,5-苯四甲酸二酐作为有机配体。使用X射线衍射,傅立叶变换红外光谱,扫描电子显微镜,能量色散X射线和荧光光谱对织物内生长的Ln-MOF进行了表征。在紫外线羔羊(345 nm)下,[受电子邮件保护的]织物和[受电子邮件保护的]织物在视觉上分别发出红色和绿色。激发-发射光谱显示了5 D 07 F 0-4跃迁和5 D 47 F 5的光谱分别在Eu-MOF和[受电子邮件保护]结构的情况下进行过渡。经过反应性染色后,[受电子邮件保护的]织物的光致发光性能得到了增强。通过研究罗丹明B(RhB)染料在织物上的光降解作用,可以评估[受电子邮件保护的]织物的自清洁功能。经过120分钟的照射时间后,RhB染料的光降解率为85–97%,这表明[电子邮件保护]织物的性能很高。这些材料有望用于高级应用,包括防护服,基于纺织品的传感器,智能标签和票证。
