| Abstract
| - The effects of hydroxyl quenching were examined on the photoluminescence properties of SnO2:Eu3+nanoparticles. High-quality SnO2:Eu3+ nanoparticles were simply synthesized from SnCl4, EuCl3, and ethyleneglycol. The photoluminescence spectra showed a reddish orange emission, which gradually increased withthe calcination temperature in the range from 700 to 1000 °C. As the calcination temperature varied, thechange of the OH-/O2- integrated-intensity ratios from X-ray photoelectron spectroscopy (XPS) wasqualitatively consistent with that of the photoluminescence intensities. The samples obtained after thehydrothermal treatment and after reheating, respectively, exhibited a decline and recovery of their emissionintensities, and this behavior with XPS confirmed the hydroxyl-quenching effect.
