The influence of Eu 3+ on the upconversion (UC) fluorescence of Er 3+ in Y 2 O 3 :Er 3+ , Yb 3+ nanocrystals was investigated. Room-temperature UC spectra show that the intensity ratio of red to green lights was increased from 8.6 to 19.3 with 1.0 mol% Eu 3+ doping. Additionally, with the increase o
