Structure Property and Visible Upconversion of Er3+ Doped Gd2O3 Nanocrystals

Keywords： optics

Gd2O3∶Er nanoparticles were prepared by a simple sol-gel method. The structure properties of Gd2O3∶Er were studied by X-ray diffraction, transmission electron microscopy, Raman spectroscopy and Fourier transform infrared spectroscopy. The visible up-converted luminescence spectra of Er3+ were investigated under excitation to 4I9/2 level by 785 nm laser. Laser power, Er3+ ion concentration and temperature dependences of the upconverted emissions were investigated to understand the upconversion mechanisms. Excited state absorption and energy transfer process are discussed as the possible mechanisms for the upconversion.
