Hydrogen Peroxide-Treated Carbon Dot Phosphor with a Bathochromic-Shifted, Aggregation-Enhanced Emission for Light-Emitting Devices and Visible Light Communication

Colloidal quantum dot light-emitting devices

Colloidal quantum dot light-emitting devices (QD-LEDs) have generated considerable interest for applications such as thin film displays with improved color saturation and white lighting with a high color rendering index (CRI). We review the key advantages of using quantum dots (QDs) in display and lighting applications, including their color purity, solution processability, and stability. After...

Quantum dot light-emitting devices with electroluminescence tunable over the entire visible spectrum.

Improvements in quantum dot light-emitting device (QD-LED) performance are achieved by the choice of organic charge transporting layers, by use of different colloidal QDs for the different parts of the visible spectrum, and by utilizing a recently demonstrated robust QD deposition method. Spectrally narrow electroluminescence of our QD-LEDs is tuned over the entire visible wavelength range from...

Graphitic Carbon Nitride/Reduced Graphene Oxide/Silver Oxide Nanostructures with Enhanced Photocatalytic Activity in Visible Light

Visible light active graphitic carbon nitride/reduced graphene oxide/silver oxide nanocomposites with a p-n heterojunction structure were synthesized by chemical deposition methods. Prepared samples were characterized by different physico-chemical technics such as XRD, FTIR, SEM, TEM and DRS. Photocatalytic activity investigated by analyzing the Acid blue 92 (AB92) concentration during the time...

Polarized Light-Emission from Photonic Organic Light-Emitting Devices

Quantum dot light emitting devices for photomedical applications.

While OLEDs have struggled to find a niche lighting application that can fully take advantage of their unique form factors as thin, flexible, lightweight and uniformly large-area luminaire, photomedical researchers have been in search of low-cost, effective illumination devices with such form factors that could facilitate widespread clinical applications of photodynamic therapy (PDT) or photobi...
