Nd/Yb-co-doped YAG transparent ceramic nano-powder was prepared by a sol-gel combustion method.The structure,morphology and properties were characterized by thermogravimetric-differential thermal analysis,X-ray diffraction,transmission electron microscopy,infrared spectroscopy,absorption analysis and fluorescence spectroscopy,respectively.The results show that the mass loss of the powder calcinated at 900 ℃ for 3 h is 49.56%.A well-crystallized Nd/Yb:YAG nano-powder with the superior sintering performance and high purity is obtained,and the morphology of the particles with the average diameter in the range of 60-100 runs appears regular.The nano-powder exhibits an intense absorption at 808 nm,corresponding to the 4I/9/2-4F7/2 transition of Nd~(~(3+) ions,which is suitable to absorb the wavelength of 808 nm from a laser diode source.The emission peak at 1046 nm of the Nd/Yb:YAG powder is more intense than that of Nd~(~(3+):YAG powder.It is indicated that the energy absorbed by Yb~(~(3+) ions from the laser diode source can be transmitted to Nd~(~(3+) ions based on the cross relaxation process of[(4F3/2)Nd,(2F7/2)Yb]-[(479/2)Nd,(2F5/2)Yb].

A well-crystallized Nd / Yb: YAG nano-powder with the superior sintering performance and high purity is obtained, and the morphology of the particles with the average diameter in the range of 60-100 runs appear regular. nano-powder exhibits an intense absorption at 808 nm, corresponding to the 4I / 9 / 2-4F7 / 2 transition of Nd ~ (3+) ions, which is suitable to absorb the wavelength of 808 nm from a laser diode source. The emission peak at 1046 nm of the Nd / Yb: YAG powder is more intense than that of Nd ~ (~ ( 3 +): YAG powder.It is indicated that the energy absorbed by Yb ~ (~ (3 +) ions from the laser diode source can be transmitted to Nd ~ (3+) ions based on the cross relaxation process of [(4F3 / 2) Nd, (2F7 / 2) Yb] - [(479/2) Nd, (2F5 / 2) Yb].
