RbYbZnSe3

RbYbZnSe₃ is a ternary semiconductor compound combining rubidium, ytterbium, zinc, and selenium elements, belonging to the family of mixed-metal selenides. This material is primarily of research interest for infrared optics and photonic applications, where its wide bandgap and optical transparency in the mid-to-far infrared region position it as a candidate for specialized optical components; however, it remains largely experimental and is not yet widely adopted in mainstream industrial production.
