Paper 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 I11/2- 4I15/2) and a ( 4F3/2- 4I11/2 ) 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.
