  • Publication number: 20240117517
    Abstract: Disclosed is an Fe-based electroplated steel sheet including: a Si-containing cold-rolled steel sheet containing Si in an amount of 0.1 mass % or more and 3.0 mass % or less; and an Fe-based electroplating layer formed on at least one surface of the Si-containing cold-rolled steel sheet with a coating weight per surface of 5.0 g/m2 or more, in which in an intensity profile measured by glow discharge optical emission spectrometry, a peak of emission intensity at wavelengths indicating Si is detected within a range from a surface of the Fe-based electroplating layer to more than 0.2 ?m in a thickness direction and not more than a thickness of the Fe-based electroplating layer, and an average value of C concentration in a region ranging from 10 ?m to 20 ?m in the thickness direction from the surface of the Fe-based electroplating layer is 0.10 mass % or less.

  • Publication number: 20230240089
    Abstract: A manufacturing method of a quantum dot ensemble of the present disclosure is a manufacturing method of a quantum dot ensemble including a plurality of core-shell quantum dots 10A that each includes a core 10B including a compound semiconductor, and a shell 10C including a compound semiconductor and covering the core, and a ligand 10D coordinated to the shell, and the manufacturing method includes mixing a core material, a shell material, and the ligand in a solvent and thereafter performing heating to thereby form the core-shell quantum dots, coordinate the ligand to the shell, and cleave the ligand.
