Ball Milling Of Lithium Niobate

Stable suspensions of iron- or copper-doped lithium niobate nanocrystals in heptane are prepared by high-energy ball milling of iron- and copper-doped bulk crystals for 25 h. The distribution of particle sizes is determined by means of dynamic light scattering with more than 90 of the crystals in the range of 10 25 nm.
