Long afterglow energy storage materials

What is long afterglow luminescent material?

Therefore, the long afterglow material is an energy storage material that can provide long-term illumination . According to the type of matrix, long afterglow luminescent materials mainly include sulfide systems, aluminate systems, silicate systems, gallate systems, and other systems.

What are the applications of Afterglow luminescence materials?

Despite the long afterglow luminescence materials have great application prospect in security signs and emergency signalization [ 1 ], persistent pigments [ 11 ], optical storage media and solar cell [ 12], photocatalysis [10, 13 ], sensors [ 14 ], fingerprint detection [ 15 ], vivo imaging [ 16 ], and drug carriers [ 17].

Why do long afterglow materials achieve round-the-clock photocatalysis?

The reason for long afterglow materials to achieve round-the-clock photocatalysis is the unique crystal structure, suitable band gap and the ability of storing electrons.

What are the applications of long afterglow material?

Nowadays long afterglow material has a wide range of applications in photocatalytic degradation [2,3], catalytic hydrogen production , photoluminescence , bio-imaging , road indication , anti-counterfeiting detection , etc.

How can epoxy resin improve the afterglow performance?

Besides, the epoxy resin was filled in the porous long persistence luminescent materials by using the method of ultrasonic oscillation. It provides optical channel inside the luminescent material and helps improve its afterglow performance by more than 40%.

Can long afterglow materials composite with other materials?

In the future, we hope that the long afterglow materials can composite with other materials to extend the carrier lifetime and expand the absorption spectrum range, thereby improving the afterglow performance and photocatalytic degradation efficiency of the afterglow materials.
