Abstract

Three types of the radical-3d/-3d-4f heterotrispin complexes [(Cu(hfac)2)4(NIT-4-OMe-4PyPh)2](1) , {[(Cu(hfac)2)3(NIT-4-OMe-4PyPh)2]}n(2) and {[Cu(hfac)2][(NIT-4-OMe-4PyPh)]2[Ln(hfac)3]}n (Ln= Gd 3; Tb 4; Dy 5; Ho 6) (NIT-4-OMe-4PyPh = 2-[4-methoxy-3-(4-pyridinylmethoxy)phenyl]-4,4,5,5- tetramethylimidazoline-1-oxyl-3-oxide; hfac = hexafluoroacetylacetonate) have been...

Hollow Co3O4/CdS Nanoparticles for Photocatalytic Hydrogen Evolution and Photodegradation

“…However, template etching would cause non-negligible nanostructure damage, which would decrease the active sites and break hollow structure to decrease solar efficiency. Hence, the porous metal–organic frameworks (MOFs) self-template auxiliarily; − for instance cobalt 2-methylimidazole (ZIF-67) is deemed as an ideal pathway. Besides adjusting the diameter quantificationally via the ZIF-67 precursor, it can also provide a sufficient Co source for formation of Co-based semiconductor metallic oxide, , while constructing a hollow nanostructure via the simple calcination to decompose organic ligands thoroughly.…”

CuI/BaSnO3 Quantum Dot/ZnSnO3 Perovskite-based Transparent p–n Junction for Photovoltaic Enhancement

“…For all these reasons, the wide bandgap of transparent devices remains a major constraint for achieving high photovoltaic conversion, primarily due to decreased carrier transport caused by excessive potential barriers. − Therefore, an easy and efficient modification approach is needed, such as metal/nonmetal doping, surface/interface microstructural modification, or other modifications. − For instance, Xu et al improved light life and carrier mobility through chlorine solubility, allowing for bandgap and stability adjustment . Among these approaches, interface quantum dot’s (QD) modification has gained attention due to its adjustable potential structure to match various p–n junction gradients and high quantum yield (QY) to increase carrier concentration. , Zhang et al used CsPbBr 3 /CsPbCl 3 QD to reduce energy loss at the double interface, as the QD’s interface layer improves film quality, energy structure, and charge transfer path .…”

Transparent p–n Junction in Cu2O/ZnS/ZnO Core–Shell Nanoarrays via In Situ Sulfuration for Enhanced Photovoltaic Stability

“…34 However, the current progress of transparent photovoltaic device has not been successful to meet the actual standards and requirements, because balancing carrier concentration and mobility has always been a bottleneck for transparent photoelectricity. 35−37 Hence, several efficient methods are being reported as a consequence of continuous research, 38,39 including surface modification and interface quantum dot modification or doping. Among these reported methods, transition layer modification with potential regulation and carrier injection has attracted considerable attention.…”
