RbBSe3

RbBSe3 is a rubidium borate selenide ceramic compound belonging to the family of mixed-anion inorganic materials that combine boron, selenium, and alkali metal elements. This is a research-stage compound studied primarily for its optical and electronic properties, particularly in applications requiring infrared transparency and nonlinear optical behavior—characteristics sought in specialized photonic and optoelectronic devices. The material's combination of heavy chalcogen (selenium) and boron makes it relevant to the development of wide-bandgap semiconductors and mid-infrared optical systems where conventional oxide ceramics fall short.
