Our natural environment inspires much of our innovation in all fields of research and application. In particular, unique optical properties are observed in natural systems such as bioluminescence and structural colors generated by bioengineering specific nanostructures. Cellulose is one such naturally occurring material that has been particularly surprising and impactful. Cellulose is one of the most abundant biopolymers with incredible versatility and distinct optical properties. Cellulose nanomaterials can readily self-assemble into chiral nematic phases which induces birefringence resulting in unique optical properties as well as causing incident irradiation to be circularly polarized. These properties unlock possibilities for cellulose materials to be used in encryption and sensing applications to name a few. Thus, cellulose materials have been used extensively as chiral scaffolds in composites but not as luminophores themselves in circularly polarized luminescent (CPL) materials. Recent discovery of the intrinsic luminescence of cellulose has expanded the use of cellulose materials in optical applications.

纤维素材料独特的光学特性

我们的自然环境激发了我们在所有研究和应用领域的创新。特别是，在自然系统中观察到独特的光学特性，例如生物发光和由生物工程特定纳米结构产生的结构颜色。纤维素就是这样一种天然存在的材料，它特别令人惊讶和有影响力。纤维素是最丰富的生物聚合物之一，具有令人难以置信的多功能性和独特的光学特性。纤维素纳米材料可以很容易地自组装成手性向列相，从而引起双折射，从而产生独特的光学特性，并使入射辐射发生圆偏振。这些特性开启了纤维素材料在加密和传感应用等领域的可能性。因此，纤维素材料已广泛用作复合材料中的手性支架，但本身并未用作圆偏振发光（CPL）材料中的发光体。最近对纤维素固有发光的发现扩大了纤维素材料在光学应用中的用途。
