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
## Abstract Tm^3+^‐doped Y~2~O~3~ nanocrystals were prepared via hydrothermal conditions at high autogenous pressure (ca. 40 MPa) using batch reactors at 220 and 250 °C for very short periods of reaction time (10 min). The as‐prepared materials were identified as Y(OH)~3~ nanoparticles. The precurs
