6 FAQs about [Phosphor energy storage principle]

What is a storage phosphor?

A storage phosphor is a material that stores a significant part of the energy released on interaction with radiation in long-living traps. In principle, it is similar to an inorganic scintillator, but the trap, which acts as the loss mechanism in a scintillator (Figure 3), functions as the memory bit in a storage phosphor.

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.

How does a memory effect affect energy storage phosphors?

This memory effect not only is expected to lead to new pressure sensing applications but also offers an approach to study charge carrier transitions in energy storage phosphors. Compounds that release light after experiencing mechanical stress can now provide optical readouts of pressure-induced events several days after they occur.

Can phosphorus be used in energy storage?

Phosphorus in energy storage has received widespread attention in recent years. Both the high specific capacity and ion mobility of phosphorus may lead to a breakthrough in energy storage materials. Black phosphorus, an allotrope of phosphorus, has a sheet-like structure similar to graphite.

Which phosphor is used for optical data storage based on photostimulated luminescence?

Wu, H. et al. Optical storage and operation based on photostimulated luminescence. Nano Energy 90, 106546 (2021). Zhang, J. M. et al.
