-Expected to be a substitute for incandescent lamp-
DGIST announced on November 20th that research team of Nano & Bio Research Division developed mechanoluminescent composite films driven by way of a naturally vibrating phenomenon.
Commercial application of the mechanoluminescence was rare so far, but the team led by Soon Moon Jeong, Senior researcher of Nano & Bio Research Division, set a foothold for exploiting mechanoluminescence in light source and imaging devices by mixing zinc sulfides (ZnS) and polydimethylsiloxane (PDMS).
As a result of the research, a warm white light of the incandescent lamp or a patterned multicolored image could be demonstrated using mechanoluminescence, and it is expected to be used for display or lighting devices.
Dr. Jeong said, "The current results are meaningful as they are expected to apply mechanoluminescence, which has been a scientific difficulty for hundreds of years, to practical use. The convergence between mechanoluminescent composite films and display or lighting technologies is also expected."
The mechanoluminescence is environmentally friendly because light can be generated by way of a naturally vibrating phenomenon (e.g., wind), therefore it is expected to be a solution for the recent environmental and resource crisis.
President Sung-Chul Shin said, "We secured the core technology to lead the environment-friendly energy technology through the development of mechanoluminescent composite films. DGIST Research Institute is showing remarkable growth in the emerging fields through convergence research."
