Abstract

Abstract. 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

摘要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。通过模拟，我们表明，实现光致发光材料通过在光谱之间转移电磁能为结构提供颜色。与用于光谱选择性吸收的传统材料（如颜料和纳米尺寸的金属谐振器）相比，通过光致发光，由于着色而产生的额外太阳能吸收更低。研究了不同类型的光致发光材料如磷光体和量子点的热性能和视觉性能。斯托克斯位移和量子产率的影响被量化，这是表征光谱之间能量位移的光致发光特性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
