Spectrally-selective monitoring of ultraviolet radiations (UVR) is of paramount importance across diverse fields, including effective monitoring of excessive solar exposure. Current UV sensors cannot differentiate between UVA, B, and C, each of which has a remarkably different impact on human health. Here we show spectrally selective colorimetric monitoring of UVR by developing a photoelectrochromic ink that consists of a multi-redox polyoxometalate and an e^- donor. We combine this ink with simple components such as filter paper and transparency sheets to fabricate low-cost sensors that provide naked-eye monitoring of UVR, even at low doses typically encountered during solar exposure. Importantly, the diverse UV tolerance of different skin colors demands personalized sensors. In this spirit, we demonstrate the customized design of robust real-time solar UV dosimeters to meet the specific need of different skin phototypes. These spectrally-selective UV sensors offer remarkable potential in managing the impact of UVR in our day-to-day life.

UVA、B 和 C 辐射的肤色特异性和光谱选择性裸眼剂量测定。

紫外线辐射 (UVR) 的光谱选择性监测在各个领域都至关重要，包括有效监测过度阳光照射。目前的紫外线传感器无法区分 UVA、B 和 C，它们对人类健康的影响截然不同。^{在这里，我们通过开发一种由多氧化还原多金属氧酸盐和电子}供体组成的光电致变色墨水，展示了 UVR 的光谱选择性比色监测。我们将这种墨水与滤纸和透明片等简单组件结合起来，制造出低成本传感器，即使在阳光照射期间通常遇到的低剂量情况下，也能提供裸眼紫外线监测。重要的是，不同肤色的紫外线耐受性不同，需要个性化的传感器。本着这种精神，我们展示了强大的实时太阳紫外线剂量计的定制设计，以满足不同皮肤光类型的特定需求。这些光谱选择性紫外线传感器在管理紫外线对我们日常生活的影响方面具有巨大的潜力。
