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.

A series of stable and color-tunable MAPbBr3−xClx quantum dot membranes were fabricated via a cost-efficient high-throughput technology. MAPbBr3−xClx quantum dots grown in-situ in polyvinylidene fluoride electrospun nanofibers exhibit extraordinary stability. As polyvinylidene fluoride can prevent the molecular group MA+ from aggregating, MAPbBr3−xClx quantum dots are several nanometers and monodisperse in polyvinylidene fluoride fiber. As-prepared MAPbBr3−xClx quantum dot membranes exhibit the variable luminous color by controlling the Cl− content of MAPbBr3−xClx quantum dots. To improve blue-light emission efficiency, we successfully introduced Ag nanoparticle nanofibers into MAPbBr1.2Cl1.8 quantum dot membranes via layer-by-layer electrospinning and obtained ~4.8 folds fluorescence enhancement for one unit. Furthermore, the originality explanation for the fluorescence enhancement of MAPbBr3−xClx quantum dots is proposed based on simulating optical field distribution of the research system.
