Sunlight-driven photocatalytic activity of SnO2 QDs-g-C3N4 nanolayers
, 2018 Herein, we reported a sunlight driven photocatalyst, SnO2 quantum dots (QDs)-g-C3N4 nanolayers (NLs) for the abatement of water pollution. SnO2 QDs were prepared in the presence of g-C3N4 NLs and the average crystallite size of SnO2 QDs was achieved ...

Synthesis of Monodisperse CdSe QDs Using Controlled Growth Temperatures
, 2011 This paper reports on the effect of growth temperatures on optical properties of monodisperse CdSe QDs synthesized via wet chemical method. The growth temperature was varied from 260 – 310 °C while growth period was fixed at 60 s. The resulting colloidal

Advanced Science, EarlyView.A dual hard‐base anchoring strategy was developed to synthesize ZnSe@ZnS:Eu3+ quantum dots, leveraging fluoride‐oleylamine interactions to create surface atomic Eu doping sites. By precisely tuning temperature, Eu3+ concentration, and fluoride levels, we obtain morphologies ranging from tip growth to coupled flower‐like structures.
