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.

Template-assisted synthesis of 2D nanosheets using nanoparticle templates

A photodetector includes a first electrode; an interlayer disposed on the first electrode; a photoabsorbing layer disposed on the interlayer, the photoabsorbing layer having one or more charge transport materials, and a plurality of two-dimensional quantum dots (2D QDs) dispersed in the one or more charge transport material; and a second electrode disposed on the photoabsorbing layer. A heterostructure photodetector includes a first electrode; a first photoabsorbing layer disposed on the first electrode, the first photoabsorbing layer having a first photoabsorbing material; a second photoabsorbing layer disposed on the first photoabsorbing layer, the second photoabsorbing layer having a second photoabsorbing material; and a second electrode disposed on the second photoabsorbing layer.

Photodetectors based on two-dimensional quantum dots

A method of producing nanoparticles comprises effecting conversion of a molecular cluster compound to the material of the nanoparticles. The molecular cluster compound comprises a first ion and a second ion to be incorporated into the growing nanoparticles. The conversion can be effected in the presence of a second molecular cluster compound comprising a third ion and a fourth ion to be incorporated into the growing nanoparticles, under conditions permitting seeding and growth of the nanoparticles via consumption of a first molecular cluster compound.

Preparation of nanoparticle materials

Methods for the synthesis of a polyoxometalate compounds include heating a metal precursor in the presence of an organic salt. The polyoxometalate compounds produced herein display high photoluminescence quantum yields and photoluminescence maximums in the blue and/or violet regions of the electromagnetic spectrum.

Octamolybdate compounds exhibiting bright emission

LED devices emitting white light comprise a blue-emitting LED, green-emitting quantum dots (QDs) and red-emitting KSiF:Mn(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.

Display devices comprising green-emitting quantum dots and red KSF phosphor

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.

Quantum dot architectures for color filter applications

Quantum dot semiconductor nanoparticle compositions that incorporate ions such as zinc, aluminum, calcium, or magnesium into the quantum dot core have been found to be more stable to Ostwald ripening. A core-shell quantum dot may have a core of a semiconductor material that includes indium, magnesium, and phosphorus ions. Ions such as zinc, calcium, and/or aluminum may be included in addition to, or in place of, magnesium. The core may further include other ions, such as selenium, and/or sulfur. The core may be coated with one (or more) shells of semiconductor material. Example shell semiconductor materials include semiconductors containing zinc, sulfur, selenium, iron and/or oxygen ions.

Cadmium-free quantum dot nanoparticles

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 AMX, wherein: A is an organic ammonium such as CHNH, (CH)(CHNH), PhCHNH, CHCHNHor 1-adamantyl methyl ammonium, an amidinium such as CH(NH), or an alkali metal cation such as Li, Na, K, Rbor Cs; M is a divalent metal cation such as Mg, Mn, Ni, Co, Pb, Sn, Zn, Ge, Eu, Cuor Cd; and X is a halide anion (F, Cl, Br, I) or a combination of halide anions.

Shelling of halide perovskite nanoparticles for the prevention of anion exchange

Materials and methods for preparing CuXSnYnanoparticles, wherein X is Zn, Cd, Hg, Ni, Co, Mn or Fe and Y is S or Se, (CXTY) are disclosed herein. The nanoparticles can be used to make layers for use in thin film photovoltaic (PV) cells. The CXTY materials are prepared by a colloidal synthesis in the presence of labile organo-chalcogens. The organo-chalcogens serves as both a chalcogen source for the nanoparticles and as a capping ligand for the nanoparticles.

A lighting fixture for promoting the development of animals comprises a backlight, such as an LED or an array of LEDs, and a series of one or more retractable, rotatable or interchangeable lenses comprising quantum dots, such that the color and/or color temperature of the light emitted by the lighting fixture can be altered and optimized during animal development. A lighting fixture adapted for use on an aquarium may be in the form factor of a standard fluorescent tube and comprise one or more LEDs and a quantum dot-containing film for down-converting at least a portion of the light emitted by the LEDs so as to provide optimum wavelengths for photosynthesis by aquarium plants while simultaneously providing attractive display lighting for the aquarium fish.
