The chemistry of colloidal semiconductor nanocrystals: From metal-chalcogenides to emerging perovskite

Nanomaterials for Biomedical Applications: Production, Characterisations, Recent Trends and Difficulties

“…This was performed utilising two-photon luminescence (TPL) imaging, CT and radio-labelling to inspect how NP size and infusion portion influence their biodistribution and intra-tumoral conveyance. These outcomes affirm that the created multifunctional GNSs can be implemented for in vivo following at various goal scales and, in addition, for image-guided PTT for the treatment of malignant growth [ 25 , 26 , 27 ]. For production of Ag and Au, the adjustment in reaction conditions, for example, pH, will prompt a difference in balance conditions.…”

“…There are distinctive core–shell structures, including (1) metalcore and different metal shell, (2) metalcore and non-metallic shell, (3) metalcore and polymer shell, (4) non-metallic core and non-metallic shell, (5) polymer core and non-metallic shell and (6) polymer core and polymer shell using different two polymers. For these six classes, the core and shell materials may be switched to tune different properties [ 27 , 32 ].…”

Status and Outlook of Metal–Inorganic Semiconductor–Metal Photodetectors

“…Lead‐halide perovskite has tunable direct bandgap, high light absorption coefficient, high carrier mobility, balanced carrier transmission distance, etc., making it a promising candidate in fields of solar cells, photodetectors, LEDs, and lasers. [ 140–147 ] Compared with the widely studied photodetectors based on organic–inorganic lead‐halide perovskite, [ 56,148–150 ] all‐inorganic lead‐halide perovskite‐based photodetectors are more stable, which have been rapidly sprouted. [ 15–18 ] In 2013, Zhou et al.…”

CsPbI3 perovskite quantum dot solar cells: opportunities, progress and challenges

“…33 Traditional QDs (CdTe, CdS/Se, PbS/Se) have been explored for the last thirty years and are well established in the light display market, while the emergence of halide perovskite QDs have paved a new avenue in solar-harvesting technology. [34][35][36][37][38][39] The synthesis of perovskite 5 QDs (PQD) is similar to traditional QDs, in which organic capping ligands are used for growth control (steric hinderance) and surface passivation, but the difference in bonding chemistry leads to the discrepancy in structure chemistry, surface chemistry, and material stability. 40,41 Among all QDs, PQDs have admirable characteristics such as narrow photoluminescence (PL), high carrier mobility, and tunable absorbance over the visible region.…”
