General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for "Energy efficiency".

Application

Organic-inorganic hybrid perovskites 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 Bis[(2-phenylethyl)ammonium] tetraiomoplumbate is 2D-layered perovskite and finds applications in semiconductors, copper (II) probing, and in LEDs.
