di-n-butylammonium lead(II) tetrabromide

Organic-inorganic hybrid perovskittes based semiconducting materials exhibit excellent properties such as long charge carrier lifetime and diffusion length, and high photolumiscence quantum yield. These properties render the perovskite materials useful for applications in light emitting diodes (LEDs), lasers and photodetectors. The di-n-butylammonium tetrabromoplumbate is 2D-layered perovskite and finds applications as violet emitter in LEDs.
