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 ...
Researchers developed core@multi-shell upconversion nanoparticles that emit full-color light, enhancing color accuracy in advanced display technologies. (Nanowerk News) Dr. Ho Seong Jang and ...
Photon upconversion involves a series of non-linear optical processes where the sequential absorption of two or more photons leads to the emission of a single photon with energy greater than the sum ...
The maximum absorption wavelength of silicon solar cells (SSCs) is approximately 1100 nm, due to the inherent bandgap limitations of silicon materials. This constraint results in significant optical ...
