摘要
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.
