Publication number: 20230130671Abstract: A metal-organic chalcogenolate (MOC) includes silver phenylselenolate functionalized with at least one functional group. The functional group may be methyl (CH3), dimethylamine (N(CH3)2), thiomethyl (SCH3), fluoro (F) trifluoromethyl (CF3), cyanide (CN), carboxy (COOH), nitrito (NO2), or alkoxy (OCxHy). The MOC can be in the form of a single crystal consisting essentially of a nanocluster (0D), a nanotube (1D), or a single monolayer (2D).Type: ApplicationFiled: October 25, 2021Publication date: April 27, 2023Inventors: William A.

Patent number: 9841544Abstract: Disclosed are a device and a method for the design and fabrication of the device for enhancing the brightness of luminescent molecules, nanostructures, and thin films. The device includes a mirror, a dielectric medium or spacer, an absorptive layer, and a luminescent layer. The absorptive layer is a continuous thin film of a strongly absorbing organic or inorganic material. The luminescent layer may be a continuous luminescent thin film or an arrangement of isolated luminescent species, e.g., organic or metal-organic dye molecules, semiconductor quantum dots, or other semiconductor nanostructures, supported on top of the absorptive layer.Type: GrantFiled: December 8, 2014Date of Patent: December 12, 2017Assignee: MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Gleb M. Akselrod, Moungi G. Bawendi, Vladimir Bulovic, Jonathan R. Tischler, William A. Tisdale, Brian J. Walker

Publication number: 20170305756Abstract: A method of preparing monodisperse MX semiconductor nanocrystals can include contacting an M-containing precursor with an X donor to form a mixture, where the molar ratio between the M containing precursor and the X donor is large. Alternatively, if additional X donor is added during the reaction, a smaller ratio between the M containing precursor and the X donor can be used to prepare monodisperse MX semiconductor nanocrystals.Type: ApplicationFiled: November 1, 2016Publication date: October 26, 2017Applicant: MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: William Tisdale, Ferry Prins, Mark Weidman, Megan Beck
