Using Lanthanide-Doped KMGF Upconversion Nanoparticles to Convert Low-Energy Photons Into High-Energy Photons
A recent breakthrough by scientists at the University of Science and Technology of China has unveiled a new application of lanthanide-doped KMGF upconversion nanoparticles (UCNs). These nanoparticles are able to convert low-energy infrared photons into higher energy visible photons, a process known as upconversion. This ability could open up a wealth of new possibilities for photonics applications, such as medical imaging, laser projection, and optical communication. By taking advantage of the unique optical properties of lanthanide-doped UCNs, researchers have developed a novel strategy to generate visible photons from low-energy infrared light. This potentially opens the door to a new class of nanoscale optical devices with unprecedented performance.
