Morphologically controlled photodetector performance of molybdenum disulfide nanostructures

CdTe QD-decorated GO nanosheet heterojunction for efficient photocurrent generation and photocatalytic activity

“…As shown by the obtained spectra, the intense absorption peak of the MB dye was observed at 663 nm. 41 The absorption intensity was found to decrease with the progress of the photocatalytic reaction, revealing that the MB dye molecules were degraded continuously during the photocatalytic process. It was observed that there were no shifts in the absorption peak except a decrease in its absorption intensity.…”

Investigations on Multiexciton Generation and Hot Electron Transfer Process in CdTe QD-Decorated TiO2 Nanostructures for Effective Photocatalytic Activity

“…Among them, one-dimensional (1D) NRs revealed better photocatalytic activity due to controlled dimensions, resulting in the discrete transmission of energy (known as nano phenomena) and delayed charge carrier recombination. However, in the case of NSs, the energy gets transmitted collectively (known as bulk phenomena) due to their uncontrolled dimensions, resulting in a faster recombination rate. , Further, to enhance the photocatalytic activity and to utilize the material properties of TiO 2 effectively, quantum dots (QDs) are preferred owing to their high extinction coefficients in the visible regime and multicarrier generation. , …”

“…10,11 Further, to enhance the photocatalytic activity and to utilize the material properties of TiO 2 effectively, quantum dots (QDs) are preferred owing to their high extinction coefficients in the visible regime and multicarrier generation. 12,13 Being zero-dimensional in nature, QDs restrict the movement of charge carriers in all three directions due to confinement phenomena. Their ability to generate multiexcitons (known as hot electrons) makes them ideal candidates for numerous applications like photocatalysis, solar cells, electronic devices, and nanocrystal lasers.…”
