Surface Defects and Symmetry Breaking Impact on the Photoluminescence of InP Quantum Dots.

To fully uncover the potential of indium phosphide (InP) quantum dots (QDs) for optoelectronics, it is crucial to understand how surface defects impact their photoluminescence (PL). To address this question, we investigate the excitonic properties of defective InP QDs using two-component density functional theory and screened configuration interaction singles. In agreement with earlier observations, we identify 3-fold coordinated phosphorus surface atoms, which function as hole traps, as the major contributors to PL.

Cutting-edge regeneration technologies for saturated adsorbents: a systematic review on pathways to circular wastewater treatment system.

Adsorption seemed like an excellent physicochemical process employed for wastewater treatment. In the last few decades, significant improvements have been made in efficiency and economy to remove contaminants from wastewater using several adsorbents. However, less attention was paid to the regeneration of used adsorbents.

Origin of the High-Frequency Shoulder in the Raman Spectra of CdSe Quantum Dots.

The origin of the high-frequency shoulder (HFS) observed above the longitudinal optical (LO) peak around 230 cm in the Raman spectra of CdSe quantum dots (QDs) has been the subject of intense debate. We use state-of-the-art density functional theory applied to small CdSe QDs with various realistic surface passivations and find an intense Raman signal around 230 cm, which corresponds to a stretching vibration of a defective 2-fold coordinated Se atom. We interpret this signal as being the origin of the HFS.

Engineering the Hot-Spots in Au-Ag Alloy Nanoparticles through Meniscus-Confined 3D Printing for Microplastic Detection.
