Organic Light Emitting Devices

The present search handles the blue light emission investigation of hybrid quantum dots organic light-emitting devices. The emissions at 445 nm and 460 nm have been examined for microcavity hybrid quantum dot organic light-emitting devices (QD-OLED) upon quantum dots of CdS and CdSe. External light emissions have been evaluated through a numerical model based on the transfer matrix for electromagnetic plane waves. The devices' optical properties are investigated based on internal reflectance and cavity length by considering the architecture consisting of multilayers thin-film structures. The overall performance of the light-emitting devices with emission at 445 nm showed an improvement of the enhancement factor and narrowing outcoupling emission relative to the devices with emission at 460 nm. Besides, the light-emitting devices based on CdS QDs revealed better performance relative to the devices based on CdSe QDs.

The Creation

In this study, we report the creation of heterostructured alloy core/shell Ag-In-Zn-S (AIZS)/ZnS quantum dots (QDs) by sequential core-forming, alloying and shelling processes and the fabrication of color-tunable QD light-emitting diodes (QLEDs) with a standard device architecture.
