Preparation of Nd-doped gadolinium-gallium garnet laser ceramic powder by sol-gel method

Abstract:

Preparation of Nd³⁺: Gd₃ Ga₅ O₁₂ polycrystalline material by sol-gel method was preparated in this paper. The structure and the pattern of the sample were analyzed by thermogravimetric analysis and differential thermal analysis (TG-DTA), Infrared spectrum, XRD, TEM and electron spectrum, which indicated that the powder with good characteristics of 70–100 nm can be obtained by sintering at 1 000°C. It was shown that the chemical composition of the sample was agreed with experimental requirements by electron spectrum analysis.
