“…In general, luminescence is defined as the radiation released by an atom due to energy absorption and an excited state. Depending on the excitation source (incident radiation, electrons, or particles) different types of phenomena (luminescence) can be distinguished: (i) photoluminescence (fluorescence or phosphorescence) when the source is an electromagnetic radiation; (ii) chemiluminescence when the source is a chemical reaction; (iii) electroluminescence, when the source is an electrical field; (iv) thermoluminescence, in which the luminescence is thermally activated; and (v) mechanoluminescence due to a mechanical action [24][25][26].…”

Fluorescence has been identified as an advantageous feature in smart fabrics, notably for the protection of humans during outdoor athletic activities, as well as for preventing counterfeiting and determining authenticity. Fluorescence in smart fabrics is achieved using dendrimers, rare earth metal compounds, and fluorescent dye. The principal method for producing fluorescent fabrics is to immerse the sample in a solution containing fluorescent agents. However, covalent connections between fluorophores and textile substates should be established to improve the stability and intensity of the fluorescent characteristics. Fabric can be fluorescent throughout, or fluorescent fibers can be woven directly into the textile structures, made of natural (cotton, silk) or synthetic (polyamide- and polyester-based) fibers, into a precise pathway that becomes visible under ultraviolet irradiation.

“…Among the latest generation of cool materials for the built environment, photoluminescent solutions have emerged owing to their ability to combine light reflection and emission [11]. Despite the numerous studies suggesting the suitability of photoluminescence for several UHI mitigation solutions, most of the research available in literature is limited to laboratory-scale investigations focused on chemical compounds [12].…”

In recent years, the use of numerical simulations to model real atmospheric conditions over cities has become increasingly popular. One of the primary objectives of these models is to assess the efficacy of various strategies for mitigating the Urban Heat Island (UHI) phenomenon. At the same time, researchers have developed and studied new adaptive materials for building applications that aim to reduce buildings’ energy consumption and improve urban microclimate conditions, while performing radiative cooling. Among the new generation of passive cooling solutions, persistent luminescent (PL) materials have emerged as a cutting-edge option for energy-saving purposes, owing to their ability to reject the incident solar radiation through both reflection and light emission. Here, the Princeton Urban Canopy Model (PUCM) is used to evaluate the potential of an advanced PL roof coating to counteract urban overheating. The phenomenon of persistent luminescence is modeled for the first time, taking advantage of experimentally obtained parameters coming from previous studies. Results demonstrate how persistent luminescence can effectively mitigate surface overheating reducing the roof’s surface temperature and net shortwave radiation up to 1.15 °C and 35 W/m2 respectively, with consequent benefits to the overall energy balance of the envelope. Such results may be further increased with the optimization of PL materials for engineering solutions.
