Researchers from the University of South Dakota and South Dakota School of Mines and Technology reported their novel fabrication of electrospinning nanofibrous thin films with a unique optical property of upconversion, in which the nanocomposite fibrous materials can emit visible light upon the excitation of near infrared light. Lanthanide-doped nanocrystals with a size below 100 nm were embedded in polymer nanofibers with upconversion properties being well preserved when they are embedded in the polymeric nanofibers. Developing novel functional sensing materials with the capability of molecular detection is of central interest for NASA’s mission on Mars exploration. The work resulted in 36 published papers and one book chapter with a total citation 285 times, as well as 34 presentations and follow-up grants from various sources such as NSF, DOD, the state of South Dakota, and various universities. The work is being conducted through a collaboration involving NASA Ames Research Center, Air Force Research Laboratory, University of Minnesota Materials Research Science and Engineering Center (MRSEC), Sinte Gleska University, Oglala Lakota College (OLC), Rice University, University of South Carolina, and Washington University, St. Louis.
