摘要:The present invention relates to metal halide perovskite (CsPbBr3) nano/microcrystals. Specifically, the present invention relates to a method for the synthesis of metal halide perovskite (CsPbBr3) nano/microcrystals. The present invention uses an easy, scalable low temperature growth of metal halide nanoparticles like CsPbBr3. The method uses a clever play on the solubility and ion exchange mechanism to precipitate nano and microcrystals of metal halide perovskites. The synthesis resulted in stable perovskite crystals with high photo- luminescence, ultralow dark current and control over their morphology. The combination of ultralow dark current, high responsivity, exceptional detectivity, and broad-band photon detection capabilities makes these crystals an excellent choice for upcoming sensors and detector technologies.

摘要:A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

摘要:A method for obtaining a salt with a general formula: RxNI, wherein: RxN is an organic cation (RxN+), R represents substituents (R—) independently selected from a group consisting of organic substituents: R1—, R2—, R3— and hydrogen (H—), x is a number of the substituents R— directly linked with the nitrogen (N) atom in the organic cation RxN+, wherein x is 3 or 4, I is an iodide anion (I−). The method comprises: preparing a reaction mixture comprising the steps of: synthesizing hydrogen iodide (HI) in situ by mixing molecular iodine (I2) with formic acid (COOH) in a molar ratio of molecular iodine (I2): formic acid (COOH) of no less than 1.01:1, in a solvent medium, introducing into the solvent medium a compound being a donor of organic cation RxN+ in an amount providing the molar ratio of the donor of organic cation RxN+: molecular iodine (I2) of no less than 1.01:1, and maintaining the reaction mixture at a temperature of not less than 20° C. for the time necessary to obtain the reaction product being the salt with the general formula RxNI. The obtained product is a substrate for synthesis of perovskites.

权利人:HINES MARGARET A; SCHOLES GREGORY D
摘要:The present invention discloses a method for synthesis of narrowly dipsersed colloidal PbS nanocrystals that offer size-tunable near-infrared emission. The stability and processibility of these near-infrared emitting quantum dots makes them ideal materials for device applications. The use of cost-effective and non-pyrophoric precursors as well as the success of larger scale reactions means the present invention provides a method for the industrial scale production of PbS nanocrystals.

摘要:A method of forming deterministic perovskite nanocrystals on a substrate is disclosed. The method includes preparing a perovskite forming precursor solution comprising a mixture of a solvent, perovskite precursors, and optionally surface passivation ligands and/or a host matrix. This perovskite forming precursor solution is deposited on a substrate by spin-coating, blade-coating or other deposition techniques to produce a layer comprising perovskite precursors, also referred to as a deposited perovskite forming precursor film. Then, a region of the film is locally heated to transform the perovskite precursors into perovskite nanocrystals and deterministically form an arbitrary pattern comprising clusters of the perovskite nanocrystals with control down to a single nanocrystal. The localized heating may be accomplished using thermal scanning probe lithography or lasers or a combination.
