Rapid and facile one-step synthesis of LiTaO3 nanorods†
Abstract
Single crystalline LiTaO3 nanorods (length of 2.5–6 μm and diameter of 200–500 nm) were synthesized via a facile molten-salt technique. An individual single crystalline nanorod exhibited a piezoelectric coefficient of 8 pm V−1. An improved optical frequency-doubling efficiency was observed in the case of LiTaO3 nanorods as compared to that of cubic crystallites of similar size.
