We propose structures that are colored with photoluminescence materials for radiative cooling applications. Using simulations, we show that implementing photoluminescence materials provides color to the structures by shifting electromagnetic energy between spectrums. Resulting additional solar energy absorption due to coloration is lower with photoluminescence compared to the traditional materials used for spectrally selective absorption, such as pigments and nanosized metallic resonators. Thermal and visual performance of different types of photoluminescence materials such as phosphors and quantum dots are investigated. Effects of Stokes shift and quantum yield, which are the photoluminescence properties that characterize the energy shift between spectrums, are quantified.

带荧光的彩色辐射冷却涂层

我们提出了用光致发光材料着色的结构，用于辐射冷却应用。使用模拟，我们表明实施光致发光材料通过在光谱之间移动电磁能来为结构提供颜色。与用于光谱选择性吸收的传统材料（例如颜料和纳米金属谐振器）相比，光致发光因着色而产生的额外太阳能吸收较低。研究了不同类型的光致发光材料（如荧光粉和量子点）的热和视觉性能。斯托克斯位移和量子产率的影响是表征光谱之间能量位移的光致发光特性，被量化。
