Ultraviolet (UV) radiation is known to promote health concerns that can manifest over both short and long terms. Aging, sunburn, skin cancer, and other conditions are related to UV radiation. Medication can also be negatively affected by this radiation. Moreover, UV radiation modifies the taste, colour, and texture of food, and may compromise its suitability for human consumption. Therefore, the development of UV-shielding materials attracts considerable research interest for numerous applications, such as UV-light resistant packaging, sunscreens, contact lenses, coatings, and even clothes. UV-shielding materials arise from the dispersion of a UV-absorber of inorganic (such as ZnO, TiO₂, CeO₂) or organic (such as lignin, nanocellulose) nature into a matrix of high transparency (usually polymer or glass based). The most common types of UV-absorbers are semiconductor particles, quantum dots, or a hybrid approach combining both.

However, inhomogeneous dispersion and large size distributions of the absorbing agent(s) usually compromise the transparency of the UV-shielding material. The goal of the current study is to present the newest and most innovative approaches regarding the development of nanostructured transparent solutions for UV-shielding.

众所周知，紫外线 (UV) 辐射会促进短期和长期的健康问题。衰老、晒伤、皮肤癌和其他疾病都与紫外线辐射有关。这种辐射也会对药物产生负面影响。此外，紫外线辐射会改变食物的味道、颜色和质地，并可能损害其对人类消费的适宜性。因此，紫外线屏蔽材料的开发吸引了众多应用的广泛研究兴趣，例如抗紫外线包装、防晒霜、隐形眼镜、涂料，甚至衣服。紫外线屏蔽材料是由无机紫外线吸收剂（如ZnO、TiO ₂、CeO ₂) 或有机（如木质素、纳米纤维素）性质转化为高透明度的基质（通常是聚合物或玻璃基）。最常见类型的紫外线吸收剂是半导体粒子、量子点或两者结合的混合方法。

然而，吸收剂的不均匀分散和大尺寸分布通常会损害紫外线屏蔽材料的透明度。当前研究的目标是提出有关开发用于紫外线屏蔽的纳米结构透明解决方案的最新和最具创新性的方法。
