Are infrared-light storage phosphors rewritable memory media?
Extensive research has been conducted on visible-light and longer-wavelength infrared-light storage phosphors, which are utilized as promising rewritable memory media for optical information storage applications in dark environments.

What phosphors are needed for optical data storage?
Furthermore, optical data storage application usually requires the storage phosphors to have a large trap depth (usually >1 eV) and high trap density to ensure storage efficiency in dark environments and high PSL efficiency upon external light stimulation.
Can PSL phosphors absorb and store energy on-demand?
The distinctive capability of PSL materials to absorb, store, and release energy on-demand has sparked extensive research and application of these storage phosphors in various critical fields, such as dosimetry, computed radiography, and optical information storage 20, 21, 22.
Do storage phosphors emit in the deep ultraviolet region?
In this case, storage phosphors emitting in the deep ultraviolet region are preferred, considering that deep ultraviolet radiation encompassing the light spectrum over 200–300 nm, does not overlap with room light and can be detected with zero background noise in a bright indoor-lighting environment 34, 35, 36, 37, 38.
