The exposure time affects the energy storage of PPRMs. PPRMs cannot be fully excited with a short exposure time. With the extension of the illumination time, more energy is absorbed by the ground state electrons, and the defect level of the phosphorescent materials is gradually saturated.

The advancement in material science and engineering technology has led to the development of antifouling (AF) coatings which are cheaper, durable, less toxic, and safe to the environment.
5. Expensive Energy Storage. The huge installation cost of solar energy systems has been a major discussion for a long time now. Energy storage cost is making the already expensive solar energy systems more expensive.
This paper summarized the development status of various reflective road markings at home and abroad. In addition, the energy storage luminescent fluorescent/phosphor marking lines in
Here λ is the wavelength, T (λ) is the spectral transmittance of the material, V (λ) is the photopic luminous efficiency of the human eye, I S (λ) is the spectral irradiance of the
Although slightly inferior to organic persistent luminescent materials in terms of biocompatibility and luminous intensity, nanocrystalline persistent luminescent materials have great advantages in the following aspects. Crystalline nanophosphors have much higher photostability, and photobleaching could be eliminated.

3.1.1. Luminescence characteristics Persistent luminescence materials absorb various light sources, including sunlight and fluorescence, and convert the accumulated light energy into visible light, which frequently consist of an inorganic matrix (known as host) and activated doping ions (activator).
Among these techniques, surface coating was found to be most effective because it improves not only capacity retention and rate capability but also the thermal stability of cathode materials for energy storage devices.
Persistent luminescent phosphors are promising for applications from bioimaging to multilevel encryption. Here, the authors review the design and preparation of persistent luminescence nanomaterials, developments in biological applications and outstanding challenges.
NIR-chargeable persistent luminescent systems can be constructed by integrating NIR-excitable up-conversion phosphors. With NIR illumination, up-conversion-integrated phosphors can be activated, and NIR photons absorbed by sensitizers (step 15) are up-converted and stored (step 16) in activators.
