Newswise — Upconversion Dr. Ho Seong Jang and colleagues at the Extreme Materials Research Center at the Korea Institute of Science and Technology (KIST) have developed an upconversion nanoparticle technology that introduces a core@multi-shell nanostructure, a multilayer structure in which multiple layers of shells surround a central core particle, and enables high color purity RGB light emission from a single nanoparticle by adjusting the infrared wavelength.
Luminescent materials are materials that light up on their own and are used in a variety of display devices, including TVs, tablets, monitors, and smartphones, to allow us to view a variety of images and videos. However, conventional two-dimensional flat displays cannot fully convey the…
