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 ...

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 ...

Photon upconversion (UC) occurs when two or more lower-energy photons are converted into higher-energy ones. Upconversion nanoparticles (UCNPs) are a key type of upconversion material. UCNPs are ...

Tunable red to green emissions in upconversion nanoparticles allow precise identification of single particles, enabling accurate, long-term multicolor tracking in complex live cell environments.

A research team has developed upconversion nanoparticles to assist in powering molecular motors. The nanoparticles can convert near-infrared radiation, which is capable of penetrating bulk material, ...

A project at the University of Science and Technology of China (USTC) has developed a contact lens allowing wearers to perceive near-IR wavelengths and see better in the dark. Described in Cell, the ...
