There is a need in the scientific world to design and develop high quality nanomaterials with multifunctional applications. In this work, we explore the molten-salt method (MSS) as a new green method for the synthesis of complex metal oxides. We adjusted all synthesis parameters such as time, temperature and pH to generate an optimum La2Hf2O7 nanoparticle with a well define shape and surface. Activator ions such as Eu3+, Tb3+, Dy3+, Bi3+ and uranium ion (U4+, U6+) were used to monitor its structural and optical behavior effect when doped.
Our results showed effective quantum yield, thermal, pressure stability, near to white light color coordinate as determined by the International Commission on Illumination (CIE) with low color coordinate temperature (CCT) for white light emitting diode (WLEDs) applications. In addition, we explore the effectiveness of our material as a scintillator for radiation detection, bio-imaging and as a nuclear waste host. All results indicate that our host material shows potential as an efficient multifunctional nanomaterial for a wide range of applications.
