2010-3-30  High-energy ball milling has been shown to be a promising method for large-scale fabrication of rare earth–transition metal nanoparticles. In this work, we report crystallographically anisotropic SmCo 5, PrCo 5 and Sm 2 (Co, Fe) 17 nanoparticles (particle size smaller than 10 nm) obtained by surfactant-assisted ball milling and study their size and properties as a function of the milling

Mechanochemical synthesis of homo- and hetero-rare

Liquid-assisted grinding in a ball mill for 20 minutes gives crystalline homo- and hetero-rare-earth(III) metal–organic frameworks by reaction between metal carbonates and benzene-1,3,5-tricarboxylic acid (H 3 BTC) in the presence of small amounts of DMF or water.

Gallium nitride powders: Mechanism of

2011-2-1  Rare earth doped GaN nanopaticles were synthesized from as-prepared GaN using a ball-mill assisted solid state reaction. The ball-milled powders were heat treated under different conditions to facilitate dopant diffusion. Luminescence properties of the rare earth doped GaN powders in the near infrared regime were investigated using a photoluminescence (PL) apparatus.
