Title: Hydrothermal method of synthesis of rare-earth tantalates and niobates

Abstract

A hydrothermal method of synthesis of a family of rare-earth Group 5 oxides, where the Group 5 oxide is a niobate or tantalate. The rare-earth Group 5 oxides can be doped with suitable emitter ions to form nanophosphors.
