Functions and Applications of Mixed-anion Compounds

Abstract

In this chapter, we will discuss the functionality of mixed-anion compounds. The first section focuses on the emergence of luminescent properties in these compounds. Various phosphors, such as SiAlON, have found extensive applications in modern technology. They serve as essential components in white LEDs, radiation dosimeters, long-persistence phosphors for luminous paints, and bioimaging. We then delve into the realm of mixed-anion based photocatalysts, which represent a significant area of research in this field. Our focus lies particularly on visible-light photocatalysts for water splitting reactions, a promising avenue towards achieving clean energy solutions. Additionally, we explore the application of mixed-anion compounds in battery materials, with special emphasis on anion batteries, as they hold great potential as next-generation energy storage devices. Finally, we conclude this chapter by discussing the exotic physical properties of mixed-anion compounds, such as superconductivity, magnetism, and thermoelectric properties. Rather than solely discussing the functionalities, our primary objective throughout this chapter remains elucidating the features of mixed-anion compounds that give rise to these functionalities.
