摘要： A template-assisted method for the synthesis of 2D nanosheets comprises growing a 2D material on the surface of a nanoparticle substrate that acts as a template for nanosheet growth. The 2D nanosheets may then be released from the template surface, e.g. via chemical intercalation and exfoliation, purified, and the templates may be reused.

摘要： LED devices emitting white light comprise a blue-emitting LED, green-emitting quantum dots (QDs) and red-emitting K2SiF6:Mn4+ (KSF) phosphor. A backlight unit (BLU) for a liquid crystal display (LCD) comprises one or more blue-emitting LEDs and a polymer film containing green-emitting QDs and KSF phosphor. The QDs and/or KSF phosphor may be encapsulated in beads that provide protection from oxygen and/or moisture.

摘要： Organically capped quantum dots are made by functionalizing the surfaces of QDs of various architectures with a combination of 6-mercaptohexanol (MCH) and 2-[2-(2-methoxyethoxy)-ethoxy]-acetic acid (MEEAA). Such MCH/MEEAA-capped QDs exhibit improved compatibility with solvents used in the fabrication of QD-containing films of light emitting devices, such as liquid crystal displays.

摘要： A core/shell semiconductor nanoparticle structure comprises a core comprising a halide perovskite semiconductor and a shell comprising a semiconductor material that is not a halide perovskite (and that is substantially free of halide perovskites). The halide perovskite semiconductor core may be of the form AMX3, wherein: A is an organic ammonium such as CH3NH3+, (C8H17)2(CH3NH3)+, PhC2H4NH3+, C6H11CH2NH3+ or 1-adamantyl methyl ammonium, an amidinium such as CH(NH2)2+, or an alkali metal cation such as Li+, Na+, K+, Rb+ or Cs+; M is a divalent metal cation such as Mg2+, Mn2+, Ni2+, Co2+, Pb2+, Sn2+, Zn2+, Ge2+, Eu2+, Cu2+ or Cd2+; and X is a halide anion (F−, Cl−, Br−, I−) or a combination of halide anions.
