Abstract

Properties of RE³⁺(Nd³⁺, Er³⁺) dopped lithium niobate(LN) nanocrystals prepared by sol-gel technique are investigated in this paper. The as-obtained LN nanocrystals are the only crystalline phase according to the X-ray powder diffraction (XRD) and transmission electron microscope (TEM) results. The absorption and emission spectra were measured in the visible and near infrared regions, and compared with that of melt-grown LN crystals. The excitation wavelength was 514 nm and 355 nm for Er³⁺ and Nd³⁺ dopped LN nanocrystal samples, respectively. A (⁴ I_11/2- ⁴I_15/2) and a ( ⁴F_3/2- ⁴I_11/2 ) near infrared lasing transition was measured at 1035 nm and 1077 nm in Er₃₊ and Nd³⁺ dopped LN nanocrystal samples, respectively. The results show red shifts in emission spectra in Er³⁺ dopped LN nanocrystal samples, and blue shifts in emission spectra in Nd³⁺ doped LN nanocrystal will be also discussed in the paper.
