© 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim Multinary nanocrystals (NCs) of I-III-VI-based semiconductors with less toxicity have attracted much attention for the fabrication of efficient light-energy conversion systems. Here we report unique photoelectrochemical properties of ZnTe−AgInTe2 solid solution (ZAITe) NCs with a controllable energy gap in near-IR region. The photoelectrochemical behavior of ZAITe NCs immobilized on an ITO electrode with a thickness of less than one monoparticle layer, resembling a p-type semiconductor photoresponse, was remarkably different from that of ZAITe NC multilayer films: The onset of a cathodic photocurrent was shifted more positively than that of the valence band maximum of ZAITe NCs and the photocurrent generation efficiency was significantly increased, when photons with energy higher than ca. 2.5 eV were irradiated. These phenomena can be explained well by the direct hot hole transfer from ZAITe NCs to the ITO electrode.

© 2018, The Author(s). Nanoparticles of I–III–VI semiconductors are promising candidates for novel non-toxic fluorescent materials. However, removal of defect levels responsible for their broad-band emission has not been successful to date. The present study demonstrates, for the first time, the coating of core AgInS2 nanoparticles—one of the I–III–VI group semiconductors with a bandgap in the visible region—with III–VI group semiconductors. The AgInS2/InSx and AgInS2/GaSx (x = 0.8–1.5) core/shell structures generate intense narrow-band photoluminescence originating from a band-edge transition at a wavelength shorter than that of the original defect emission. Microscopic analyses reveal that the GaSx shell has an amorphous nature, which is unexpected for typical shell materials such as crystalline lattice-matching ZnS. Single-particle spectroscopy shows that the average linewidth of the band-edge photoluminescence is as small as 80.0 meV (or 24 nm), which is comparable with that of industry-standard II–VI semiconductor quantum dots. In terms of photoluminescence quantum yield, a value of 56% with nearly single-band emission has been achieved as a result of several modifications to the reaction conditions and post-treatment to the core/shell nanoparticles. This work indicates the increasing potential of AgInS2 nanoparticles for use as practical cadmium-free quantum dots.

Multinary I-III-VI2 group semiconductor nanocrystals, such as CuInS2, Cu(InGa)Se2, AgInS2 and their solid solutions with ZnS, have been attracting increasing attention due to their low toxicity, wide range of absorption from UV to visible or near-infrared regions, and tunable energy gap. In this review, we introduce recent progress of solution-phase syntheses of high-quality multinary nanocrystals, which are candidates for alternative materials of Cd- and Pb-based binary nanocrystals showing high toxicity. Physicochemical properties of multinary nanocrystals are tunable depending on their crystal size and chemical composition. For example, nanocrystals of solid solution between AgInS2 and ZnS exhibited strong photoluminescence, the color of which was controlled from red to green with an increase in the ZnS fraction. The controllability of their photochemical properties is useful to develop novel photofunctional materials for the applications, such as photocatalyst and biomolecule marker.

Inorganic semiconductor multilayer thin films of CdS nanoparticles and titania nanosheet (TNS) were prepared by an electrostatic layer-by-layer accumulation technique. The absorbance of immobilized CdS and TNS linearly increased in proportion to the number of accumulated films, but the photoluminescence of CdS nanoparticles was dramatically quenched by being tucked into the TNS layer. Accumulation of the TNS/CdS layer remarkably enhanced the photocurrent generation compared to the case of films layer-by-layer-deposited with CdS nanoparticles and polystyrene sulfonate of an inert polymer. These observations can be explained by the efficient photoinduced electron transfer from photoexcited CdS nanoparticles to adjacent TNS layers.

Nano-ordered hybrid films of layered double hydroxide (LDH) nanosheets and two types of anionic dye molecules, i.e. tetrakis(4-carboxyphenyl)porphyrin (TCPP) and 1,3,6,8-pyre-netetrasulfonic acid (PTSA), were prepared by a layer by-layer deposition (LBL) method. Photo-induced energy transfers (PET) between the PTSA and TCPP layers were investigated for two differently stacked structures of the TCPP/LDH/PTSA hybrid films, Le; (a) PTSA/LDH multilayers independently stacked on the TCPP/LDH multilayers to form (TCPP/LDH)(n)/(PTSA/LDH)(n) and (b) TCPP/ LDH and PTSA/LDH monolayers deposited alternately to form [(TCPP/LDH)/(PTSA/LDH)](n) hybrid films, which were both prepared by varying the successivie-and alternate stacking of-the (TCPP/LDH) and (PTSA/LDH) unit layers. A Foerster type resonance energy transfer is observed in the present hybrid films, where the efficiency of PET was strongly affected by changing the distance between the TCPP and PTSA molecules in the (TCPP/LDH)(3)/(PSS/LDH)(m)/(PTSA/LDH)(3) hybrid films (m = 1-10) obtained by the insertion of the photochemically inert poly (styrenesulfonic acid) (PSS) and LDH hybrid layers, i.e. the insertion of (PSS/LDH). between the (TCPP/LDH), and (PTSA/LDH), layers.
