The optical properties of afterglow luminescent particles in mechanical quenching and mechanical luminescence have aroused great interest in various technological applications. However, for specific photon applications, clearer explanations are needed for these unusual events.

Recently, scientists from Pohang University of Science and Technology have designed an optical display technology with ALP that can write and erase messages underwater. This discovery reveals a unique optical phenomenon in ALP, and they have also created a device to achieve this phenomenon.

ALP can absorb energy and gradually release it, exhibiting mechanical luminescence when subjected to external physical pressure and mechanical quenching, where the emitted light gradually disappears.

In this study, scientists delved into the effects of captured electrons and charging on mechanical luminescence and quenching.
They identified the potential mechanisms behind these two events. Based on this knowledge, they paired ALP with an extremely thin polymer material that can simultaneously achieve both phenomena. This combination has led to the development of optical display patches that can be attached to the skin.

Just press with your finger and the display screen patch can write information. When exposed to ultraviolet radiation, the patch will reset to a blank state, just like using an eraser to delete text from a notebook. In addition, touch screen displays also have moisture resistance, allowing them to continue working even after prolonged immersion in water.

Professor Sei Kwang Hahn, who led the research, said, "It can serve as a communication tool in situations where communication options are limited, such as underwater environments characterized by low light or high humidity. It will also be used in wearable photon biosensors and phototherapy systems in extreme environments.".
