Project summary:
This project focuses on the development of environmentally friendly and cost-effective materials for high-tech optical applications, with an emphasis on cubic spinels. These adaptable materials, when doped with transition metal ions, exhibit great potential in a wide range of technologies, including UV and solar-blind photodetectors, pc-wLEDs, scintillators, near-infrared (NIR) emitters, and luminescent markers. We will design and synthesize multicomponent oxide spinels across a broad compositional space, including the potential formation of high-entropy compounds. By employing group-action symmetry analysis, we will identify structurally unique candidates for computational evaluation and targeted synthesis. Transition metal-doped multicomponent spinels offer significant advantages for NIR emission, overcoming the limitations commonly encountered in simpler two-component systems. Inspired by recent advancements in high-entropy materials, this project seeks to open new directions in the field of optical materials by exploring complex spinel compositions and applying advanced theoretical and experimental frameworks to study and optimize their functional properties.
