Rapid synthesis of single-crystalline TbF3 with novel nanostructure via ultrasound irradiation

▶ Research highlights ▶ TbF3 nanopeanut was prepared via sonochemical method. ▶ The morphologies of TbF3 can be tuned by ultrasound irradiation and fluoride source. ▶ The TbF3 nanopeanut shows high photoluminescence intensity.
