“…This was attributed to the widening of the bandgap of the core-shell quantum dots due to the larger bandgap of the ZnS shell compared to the CdSe core, which further led to the blue shift of the PL peak when the thickness of the ZnS shell of the quantum dots is increased to a certain extent. [35][36][37] As can be verified from Fig. 1a, the quantum dot core's absorption intensity gradually diminished as the coating of the quantum dot shell increases.…”

“…The newly developed hot‐injection synthesis method is able to realize the rapid fabrication of a wide range of QDs (PbSe QDs, 68 CdSe/ZnS core‐shell QDs, 69 and CsPbX 3 QDs 70 ). For hot‐injection synthesis, generally, the metal precursor solution and ligand solution are rapidly injected into the high‐temperature solvent (trioctylphosphate [TOP], trioctylphosphine oxide [TOPO], or 1‐octadecene [ODE], etc.)…”

Photocatalytic water splitting is beneficial for the effective mitigation of global energy and environmental crises. Owing to multi‐exciton generation, impressive light harvesting, and excellent photochemical properties, the quantum dot (QD)‐based catalysts reveal a considerable potential in photocatalytic hydrogen (H2) production compared with bulk competitors. In this review, we summarize the recent advances in QDs for photocatalytic H2 production by enumerating different synthetic and characterization strategies for QDs. Various QDs‐based photocatalysts are introduced and summarized in categories, and the role of different QDs in varied systems, as well as the mechanism and key factors that enhance the photocatalytic H2 generation performance, is discussed. Finally, conclusions and future perspectives in the exploration of highly efficient QDs‐based photocatalysts for innovative applications are highlighted.

“…Conductivity, Ohm −1 × cm −1 Content, cm −3 Charge Carrier Mobility, cm 2 × V −1 × s −1 It should be noted that the doping process of the different materials using the perspective nanostructures-fullerenes, carbon nanotubes (CNTs), quantum dots (QDs), graphene oxides (GrO), etc.-provokes the dramatic change in the basic physical-chemical material properties vital for the improvement of the technical device parameters [21][22][23][24][25][26][27][28][29][30][31][32][33]. Thus, the role of fullerene C60 in controlling the performance of inverted perovskite solar cells was shown in [21].…”

Due to the high demand for optoelectronics for use in new materials and processes, as well as the search for their modeling properties, the expansion of the functionality of modified materials using nanotechnology methods is relevant and timely. In the current paper, a specific nanotechnology approach is shown to increase the refractive and photoconductive parameters of the organic conjugated materials. The sensitization process, along with laser treatment, are presented in order to improve the basic physical–chemical properties of laser, solar energy, and general photonics materials. Effective nanoparticles, such as fullerenes, shungites, reduced graphene oxides, carbon nanotubes, etc., are used in order to obtain the bathochromic shift, increase the laser-induced change in the refractive index, and amplify the charge carrier mobility of the model matrix organics sensitized with these nanoparticles. The four-wave mixing technique is applied to test the main refractive characteristics of the studied materials. Volt–current measurements are used to estimate the increased charge carrier mobility. The areas of application for the modified nanostructured plastic matrixes are discussed and extended, while also taking into account the surface relief.
