Solvothermal Synthesis of Sodium and Potassium Tantalate Perovskite Nanocubes

A low-temperature solution-based synthetic method was developed for the synthesis of nanocubic structures of alkali tantalates. Two kinds of highly pure tantalate single crystalline nanocubes with the edge length of about 5 and 16 nm were synthesized successfully without introducing any templates or catalysts.
