Scientists have developed an optical display based on mechano-optical mechanisms.
Optical properties of afterglow luminescent particles in mechanoluminescence and mechanical quenching have attracted great attention for diverse technological applications. Recently, a team of researchers from Pohang University of Science and Technology has garnered attention by developing an optical display technology with ALPs enabling the writing and erasure of messages underwater.
In this research, the team delved into the impact of trapped electrons and recharging on both mechanoluminescence and quenching. They successfully unraveled the mechanisms governing both phenomena. Building on this understanding, they combined ALPs capable of simultaneously realizing both phenomena with a very thin polymeric material . This combination resulted in the creation of an optical display patch that can be attached to the skin.
Professor Sei Kwang Hahn who led the research stated,"It could serve as a communication tool in situations with limited communication options such as underwater environments characterized by low light or high humidity." He further remarked,"It would be also used for wearable photonic biosensors and phototherapy systems in extreme environments."
Researchers have developed a new all-optical method for driving multiple highly dense nanolaser arrays. As described in Optica, the approach could enable chip-based optical communication links that ...
