White light emitting diode prototypes based on cadmium sulfide and graphene carbon quantum dots
Keywords:
Down conversion, Stokes’s shift, Surface defects, CdS QDsAbstract
During the last years, semiconductor quantum dots (QDs) have attracted great attention due to the outstanding properties for solid-state lighting, display technology, biosensors, among others. White light emitting diodes (WLEDs) using down conversion approach is one of the new attractive alternatives in solid-state lighting. However, these devices present several shortcomings as near-UV light escape and
QD-polymer incompatibility. In this work, we propose alternative
