Optical properties of afterglow luminescent particles (ALPs) in mechanoluminescence (ML) and mechanical quenching (MQ) have received a lot of spotlight. Recently, scientists have noted that it can impact several technological applications. It is also known to be widely applicable in many fields, and this has made it a gem. A research team has received significant attention after making a groundbreaking development in optical display technology. These researchers are from Pohang University of Science and Technology (POSTECH).
The team uncovered a remarkable optical phenomenon with ALPs, which aids in underwater writing and the erasure of messages. The researchers are the first to create a device that could successfully implement this phenomenon. Afterglow luminescent particles (ALPs) are materials with optical properties that can trap the irradiated photon energy in defect states. It then releases this absorbed energy gradually and displays it as light. The APLs exhibit mechanoluminescence when subjected to external physical pressure.
