New Generation Optical Nanotransformers for NIR-to-Visible Image Up-Conversion and Friend-Foe Identification
Abstract
In this project, we explored new generation photon conversion nanomaterials that can harvest light over a broad spectral range and subsequently convert it with a spectral shift. We have developed new pathways involving energy harvesting by a strong dye absorber and subsequent energy transfer to a lanthanide ions in the nanocrystals. The introduction of this new pathway allowed us to address the fundamental limit of the weak and narrow IR absorption of rare-earth upconverters, as long as the concentration quenching of rare earth elements themselves. This type of lanthanide doped materials holds the great potential because they can tolerate harsh environments and easily scale up to produce.
