Achieve White Light by Utilizing Interface Defects on Simplified Ultraviolet Organic Light Emitting Diodes

摘要

A simplified bilayer ultraviolet organic light emitting diode(UV-OLED) with broadband spectrum has been demonstrated. This device achieved a near-white light at high voltages. The recombination zone has been known by inserting ultrathin film of Rubrene. The electroluminescence spectra was measured to elucidate the recombination zone shift by voltage increasing.
