Direct analysis in real-time mass spectrometry (DART-MS) has been applied to the characterization of colloidal nanocrystal surface ligands. The nanocrystals (NCs) in colloidal suspension were purified and deposited onto a solid substrate, and the sol

Surface defects and organic surface-capping ligands affect the photoluminescence properties of semiconductor quantum dots (QDs) by altering the rates of competing nonradiative relaxation processes. In this study, broadband two-dimensional electronic

In this work we demonstrate enhancement in visible-light photocatalytic activity (PCA) of ZnO nanoparticles (NPs) with minimal attenuation of visible light transmittance. This approach can benefit numerous optoelectronic and photocatalytic applicatio

Perovskite solar cells (PSCs) based on methylammonium lead iodide (CH 3 NH 3 PbI 3 ) have shown unprecedentedly outstanding performance in the recent years. Nevertheless, due to the weak interaction between polar CH 3 NH 3 + (MA + ) and inorganic PbI

When quantum dots (QDs) are irradiated with light, they are subject to photoinduced phenomena, such as photooxidation, photoluminescence (PL) blue-shift, photodarkening (PD) and photobrightening (PB). Some applications of QDs require their dispersion

A method for producing PbS nanocrystals using air stable precursors is examined and compared to existing methods. The method employs thermal decomposition of thiocarbonyls to produce the reactive sulfide needed to react with lead oleate. Thioacetamid
