Introduction

The charged phosphor exhibits solar-blind ultraviolet (200–280 nm) emission under sunlight, while its persistent luminescence is nearly absent in a dark environment, revealing the role of sunlight in releasing the stored energy of the phosphor. Herein, we introduce a glow-in-the-daylight phenomenon, which is essentially photostimulated luminescence of ultraviolet phosphor upon stimulation by polychromatic daylight. As a proof of concept, imaging and spectral experiments are carried out using an x-ray-charged L u P O 4: P r 3 + phosphor to. Storage phosphors, known for their delayed emission after charging, have shown great potential for applications in radiation detection, bio-imaging, and medical diagnosis. Despite their promise, the underlying mechanisms governing their charging behavior have not been sufficiently investigated. In. Phosphor-converted LEDs (pc-LEDs) have gained significant attention since they could act both as an energy source for photosynthesis and a power source in sprouting, blossoming, fruiting, and other photomorphogenesis. The evolution of plant illumination and the advantages and disadvantages of. Abstract: In natural photosynthesis, light-driven electron transfer across the thylakoid membrane enables efficient charge separation and the confinement of reaction spaces for generating NADPH and CO2 and oxidation of water. These reactions are complementary redox reactions and require different.
