Lanthanide luminescence could be quenched by water or high frequency vibrations, which seriously limit the application of luminescent composites, especially hydrogels based on lanthanides. Here, luminescent hydrogels were fabricated by introducing 5-sulfosalicylic acid molecules into a hybrid system which stemmed from the self-assembly of sodium alginate with terbium ions (Tb3+). The shape of the enhanced luminescent hydrogels was not limited, as both layered and spherical hydrogels can be prepared. The morphology and luminescence properties of the hydrogels were thereafter studied. The results showed that the as-prepared alginate hydrogels exhibited clearly identified green emissions under ultraviolet radiation through the metal coordination interactions with the assembled alginate, while the luminescence intensity of the alginate hydrogels increased with increasing reaction time between the alginate and Tb3+ ions. Even, when dried, the hydrogels still exhibited enhanced luminescence, which might be used twice. The results demonstrated that 5-sulfosalicylic acid synergistic terbium–polymer self-assembly is an effective approach to fabricate luminescent composites containing terbium complexes.

海藻酸盐基水凝胶的发光特性表征和研究†
镧系元素的发光可以被水或高频振动淬灭，这严重限制了发光复合材料的应用，尤其是基于镧系元素的水凝胶。在这里，通过将5-磺基水杨酸分子引入到混合系统中来制备发光水凝胶，该混合系统源于海藻酸钠与ter离子（Tb 3+）。增强型发光水凝胶的形状不受限制，因为可以制备层状和球形的水凝胶。此后，研究了水凝胶的形态和发光特性。结果表明，所制备的藻酸盐水凝胶在紫外辐射下通过与组装的藻酸盐的金属配位相互作用表现出清晰的绿色发射，而藻酸盐水凝胶的发光强度随藻酸盐和Tb 3+之间的反应时间的增加而增加。离子。即使干燥后，水凝胶仍会显示出增强的发光度，可以使用两次。结果表明，5-磺基水杨酸协同的-聚合物自组装是制备含ter配合物的发光复合材料的有效方法。
