Description

General description

This product is a violet emmiter for light emmiting diodes. It is solution processable in DMF to create thin films. This material has a photoluminescence peak at 407 nm with a quantum yield of 26% as nanoplatelets. Single crystals have been grown with a 412 nm emission of and quantum efficiency of 0.22(1). LED devices using this material as the emissive layer have been constructed that opperate at room temperature with an on/off voltage of 2.5-2.8 V and external quantum efficiency (EQE) of 0.038%.

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

di-phenylethylammonium lead(II) tetrabromide can be used in the field of solar cells and photovoltaic devices as a precursor material for the synthesis of lead halide perovskite thin films, which have shown promising efficiency in solar energy conversion. di-phenylethylammonium lead(II) tetrabromide based perovskite materials have been studied for their potential in optoelectronic devices such as light-emitting diodes (LEDs), lasers and photodetectors.
