Exploration of long afterglow luminescence materials work as round-the-clock photocatalysts

A brief review: the application of long afterglow luminescent materials in environmental remediation

“…Hai et al used decorated Ag/Sr 2 MgSi 2 O 7 :Eu 2+ , Dy 3+ (SMS) as a photocatalyst with unique carrier transport paths and large number of crystal defects, where Ag was introduced in the LAL material for enhancing its performance. 47 Under UV irradiation, the decomposition rate of RhB was 45.1% by Ag/SMS, and the degradation rate of RhB reached 76.5% aer 24 h in the dark, with the nal degradation rate as high as 88.9%. The reason for the efficient photocatalytic degradation was that Ag interfaced on the SMS with a suitable bandgap can enable the separation of electrons and holes.…”

Research progress on near-infrared long persistent phosphor materials in biomedical applications

“…The raw materials mixed by the ball mill were heated under certain temperatures and conditions. 112,113 The use of co-solvents such as P 2 O 5 and B 2 O 3 was discovered to lower the sintering temperature and improve the material's afterglow qualities. 114 Although the above synthesis method is simple and low-cost, it requires long-time high-temperature sintering and the prepared product is damaged by ball milling, which reduces the afterglow performance of the material.…”

Glow in the Dark Median Frontage and Pedestrian as a Guide for Drivers at Night

“…This understanding is based on the fundamental properties of phosphorescence. Phosphor glows in the dark and, when exposed to a light source, it absorbs light energy and stores it as electronic energy (Hai et al, 2021). When the light source is removed, the stored energy is released as light, creating a glow-in-the-dark effect.…”
