TL;DR: This work conducted spectroscopic studies of the excitons and biexciton dynamics in single CsPbBr3 perovskite quantum dots and found that while the rates of radiative recombination remain essentially constant, the overall relaxation process is dominated by nonradiative recombinations of single exciton and bIExcitons.

TL;DR: In this article, a review highlights state-of-the-art research on tuning optical properties of atomic-layered MoS2 (including monolayer and few-layer MoS 2), and proposed mechanisms of these modulations are discussed.

TL;DR: An external electron transfer model is proposed to analyze the possible effect of radiative, nonradiative, and electron transfer pathways on fluorescence blinking andoretical analysis based on the model combined with measured results gives a quantitative insight into the blinking mechanism.

TL;DR: In this paper, the adsorption performance of contaminants with different adsorbents and co-adsorbates under identical conditions was investigated in a single component system and in the presence of cationic methylene blue (MB) dye as well as heavy metal ion Pb2+ were explored.

TL;DR: It is shown that the survival time of singleQDs, the on-state probability of PL intensity traces, and the total number of emitted photons are significantly increased for single QDs in PPD compared with that on glass coverslip.
