Pure Green Ag–In–Ga–S/Ga–S Quantum Dot Light‐Emitting Diodes with Electron Transport Materials Exhibiting Enhanced Luminescence Properties
Autor: Genichi Motomura, Satoru Ohisa, Taro Uematsu, Susumu Kuwabata, Tatsuya Kameyama, Tsukasa Torimoto, Yoshihide Fujisaki
Publikováno v: Advanced Physics Research, Vol 3, Iss 10, Pp n/a-n/a (2024)
Abstract Quantum dots (QDs) are essential luminescent materials with applications in wide‐color‐gamut displays requiring exceptional color reproducibility. Multinary semiconductor QDs composed of groups I, III and VI elements are expected to serv

Solution-phase Synthesis and Photoelectrochemical Properties of Ag8SnSe6 Quantum Dots with Different Sizes
Autor: Nurmanita RISMANINGSIH, Takayuki TAKIYAMA, Kazutaka AKIYOSHI, Tatsuya KAMEYAMA, Tsukasa TORIMOTO
Publikováno v: Electrochemistry, Vol 92, Iss 7, Pp 077005-077005 (2024)
Ternary Ag8SnSe6 quantum dots (QDs) were synthesized via a heating-up method in which the reaction of corresponding metal acetates and selenourea was carried out at 250 °C in oleylamine containing 1-dodecanethiol (DDT) as a capping ligand. The obtai

Photoluminescence Redshift of AgInS2 Quantum Dots by Employing Shells with Graded Composition
Autor: Navapat KROBKRONG, Taro UEMATSU, Tsukasa TORIMOTO, Susumu KUWABATA
Publikováno v: Electrochemistry, Vol 91, Iss 10, Pp 107001-107001 (2023)
Silver indium sulfide (AIS)/gallium sulfide (Ga–S) core/shell QDs exhibit a narrow band-edge photoluminescence (PL) in the yellow color region, and shifting the PL wavelength is crucial for optical applications. In this study, we attempt to redshif

Optical force mapping at the single-nanometre scale
Autor: Junsuke Yamanishi, Hidemasa Yamane, Yoshitaka Naitoh, Yan Jun Li, Nobuhiko Yokoshi, Tatsuya Kameyama, Seiya Koyama, Tsukasa Torimoto, Hajime Ishihara, Yasuhiro Sugawara
Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-7 (2021)
Direct visualisation of 3D vector distributions of photoinduced fields can shed light on the optical and mechanical behaviour of different materials. Here, the authors demonstrate such visualisation using photoinduced force microscopy by observing th

Emission tuning of AgInS2-based core/shell semiconductor quantum dots with type-II and quasi-type-II band alignments
Autor: Navapat Krobkrong, Taro Uematsu, Tsukasa TORIMOTO, Susumu Kuwabata
Publikováno v: Japanese Journal of Applied Physics.
Here, silver indium sulfide (AgInS2/gallium selenide core/shell quantum dots (QDs) were developed to exhibit red band-edge emission. Previously, we developed AgInS2/gallium sulfide core/shell QDs, which exhibited yellow band-edge photoluminescence (P
