本研究以低温碱金属氢氧化物/尿素水溶液为纤维素溶剂，通过原位掺杂制备了嵌有镧系离子纳米粒子的纤维素水凝胶。根据组成镧系元素离子的类型和相对浓度，通过以一定比例混合红色、绿色和蓝色来调制光发射的颜色以产生三原色和其他调整的颜色。本工作为制备可调控的荧光纤维素水凝胶开辟了新的途径，在生物成像和荧光免疫分析领域具有潜在的应用前景。
In this study cellulose hydrogels with lanthanide ions nanoparticles embedded in were prepared via in situ doping using a low-temperature alkali hydroxide/urea aqueous solution as a cellulose solvent. Depending on the type and relative concentrations of the constituent lanthanide ions, the color of light emission were modulated to generate the three primary colors and other adjusted colors by blending red, green and blue at certain ratios. This work has opened new and convenient pathway to create regulated fluorescent cellulose hydrogels for potential applications in the fields of bioimaging and fluoroimmunoassay.
