Abstract

The development of multifunctional materials is crucial for addressing the growing demands in medical and sustainable energy applications. In this context, rare-earth-based double perovskites have garnered attention due to their tunable physical properties. This study explored the structural, electronic, optical, mechanical, thermal, and thermoelectric properties of Sr₂NdNbO₆ and Sr₂TmNbO₆ for potential applications in medical and sustainable energy technologies. Both double perovskites exhibited half-metallic behavior with direct band gaps (3.19 eV for Sr₂NdNbO₆ and 3.09 eV for Sr₂TmNbO₆), making them suitable for UV optoelectronics, including photodetectors and biosensors. Both Sr₂RENbO₆ (RE= Nd, Tm) double perovskites demonstrated better thermoelectric efficiency, while Sr₂NdNbO₆ showed a higher Seebeck coefficient and enhanced UV response, suitable for antibacterial or sterilization applications. Their mechanical stability supported potential use in implantable or radiation-shielding devices. These multifunctional properties underscore their promise for advanced medical and energy-related technologies.
