Paper Abstract

Infrared-to-visible upconversion emission intensities are investigated in Li+/Er3+, Li+/Ho3+/Yb3+ and Li+/Tm3+/Yb3+ codoped oxide nanocrystals. By introducing Li+ ion, the upconversion emission intensity of rare-earth ions are significantly enhanced comparing with that without the Li+ ion. The local structure around Er3+ and Ho3+ ions are studied by the extended X-ray absorption fine structure spectroscopy. After doping Li+ ion, both the average bond lengths of Er-O and Ho-O are decreased.
