摘　　要：分别采用液相法和固相法制备的纳米粉,制得透明性良好的Nd∶(Y0.9La0.1)2O3透明陶瓷,并测试了各样品的结构,光谱及光学性能.结果表明:该陶瓷具有相同的光谱性能;但液相法复合纳米粉制备的透明陶瓷光学性能优于固相反应法制备的透明陶瓷;固相反应法制备的透明陶瓷,由于有部分La2O3分布不均,易导致晶粒生长不均匀和残留少量气孔;长时间球磨混料,也不利于样品性能的提高.Nd∶（Y0.9La0.1）2O3 transparent ceramics are fabricated with wet-chemical composite nano-powders and solid-state reaction nano-powders,respectively. Their microstructure,optical and spectral properties are investigated. The experimental results show that both samples own the same spectroscopic properties,while the samples fabricated by wet-chemical composite nano-powders have better optical properties due to the uniform mixing of the raw materials. The worse performances of the samples fabricated with solid-state reaction nano-powders are ascribed to the inhomogeneous dispersion of La2O3 in the processing of mechanical ball-milling,which cause unevenly grains and few left pores. Long time ball-milling will deteriorate the optical properties of the samples prepared by solid-state reaction method.
