Abstract：Nanocrystals were prepared by stearic acid gel method. The structure and morphology of nanocrystals were characterized by X-ray powder diffraction (XRD), transmission electron microscope(TEM) and infrared spectra. Experimental results show that the absorption peaks of La2O3 extendwith their blue shift or red shift. The absorption of La2O3 nanocrystals is good in the wavelength range of 1 000 to 1 700 nm, where La2O3 nanocrystals may serve as a kind of absorbent of laser camouflage material.
