摘 要：Ultra-fine Nd:YAG powders with different doping concentrations were synthesized by sol-gel combustion method.The pure Nd:YAG could be prepared at the low temperature of 900 oC.Ethanol could improve the dispersity of powders,and the average size of the ul-tra-fine powders was around 250 nm.The reflection spectrum showed that there were several apparent characteristic absorption peaks and the intensity of these peaks enhanced with the increasing concentration of Nd3+.The luminescence spectrum,which was excited by 808 nm wavelength,exhibited several obvious emission bands in the range of 900–1150 nm.The emission intensity of Nd:YAG powders increased until the Nd content was above 3 mol.% due to the fluorescent quenching effect.
