InGaN/GaN based LEDs with electroluminescence in violet, blue, and green tuned by epitaxial growth temperature
In this work, we present a full set of InGaN LEDs based on a single optimal InGaN/GaN quantum design with emission wavelengths spanning from green to blue to violet by tuning the active layer growth temperature to precisely ...
White light generation with azide functionalized polyfluorene hybridized on near-UV light emitting diode
We present white light generation using poly[(9,9-dihexylfluorene)-co-alt- (9,9-bis-(6- azidohexyl)fluorene] (PFA) for the first time. Hybridizing PFA on near-UV LED, we demonstrate high color rendering index up to 91.0.
Near-UV InGaN/GaN-based dual-operation quantum optoelectronic devices
We present a novel dual-operation InGaN/GaN based quantum optoelectronic device (QOD) that operates as a quantum electroabsorption modulator in reverse bias and as a light emitter in forward bias in the spectral range of ...
Multi-layered CdSe/ZnS/CdSe heteronanocrystals to generate and tune white light
In this study, tuneable white light generation by controlling CdSe/ZnS/CdSe core/shell/shell heteronanocrystals integrated on InGaN/GaN light emitting diodes was presented. These multilayered quantum dots, also known as ...
Increased quantum efficiency and reduced red-shift in polymer nanoparticle luminophors
In this paper, using a polyfluorene derivative, increased fluorescence quantum efficiency and reduced red-shift in the film form of polymer nanoparticle luminophors is achieved, when compared to directly spin coated polymer ...
