compound introduction

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%.} Description This product is a violet emmiter for light emmiting diodes.
