Abstract: A photodetector for detecting deep ultra-violet light includes a substrate; first and second electrodes separated by a channel; and colloidal MnO based quantum dots formed in the channel. The colloidal MnO based quantum dots are sensitive to ultra-violet light having a wavelength lower than 300 nm.

Abstract: Provided are methods, systems, and apparatuses providing flexible conductive substrates for nanomaterial/perovskite-based optoelectronic devices. One such apparatus may include a flexible conductive substrate, a nanomaterial layer disposed on the flexible conductive substrate, and a perovskite layer disposed on the nanomaterial layer. The flexible conductive substrate may be a cost-effective metal sheet such as a stainless steel sheet or an aluminum sheet. The nanomaterial layer may comprise semiconductor or oxide nanorods, nanowires, nanotubes, or nanoparticles, such as gadolinium-doped zinc oxide nanorods. The perovskite layer may comprise inorganic or organic perovskite. The apparatus may further include an optically transparent conductive layer disposed on the perovskite layer. Optionally, the apparatus may include an electrical contact disposed on a portion of the optically transparent conductive layer.

Abstract: Methods, apparatuses, and systems are provided for using laser ablation to manufacture nanoparticles. An example method includes steps of generating, by a laser beam generator, a laser beam, splitting, by a set of beam splitters, the laser beam into a plurality of derivative laser beams, and directing each derivative laser beam towards a plurality of targets. In this example method, the plurality of targets are submerged in corresponding synthesis solvents within corresponding synthesis chambers. Moreover, interaction of each derivative laser beam with its corresponding target releases nanoparticles into the corresponding synthesis solvent to create a nanoparticle solution including both the corresponding synthesis solvent and the released nanoparticles.

Abstract: A method for forming CsPbBr3 perovskite nanocrystals into a two-dimensional (2D) nanosheet includes providing CsPbBr3 perovskite nanocrystals; mixing the CsPbBr3 perovskite nanocrystals into a mixture of a first solvent and a second solvent, to form a solution of the CsPbBr3 perovskite nanocrystals, the first solvent, and the second solvent; and forming an optoelectronic device by patterning the CsPbBr3 perovskite nanocrystals into a nanosheet, between first and second electrodes. The first solvent is selected to evaporate before the second solvent.

Abstract: Methods for configurable and proactive application diagnostics and recovery are performed by systems and devices. A diagnostics manager determines diagnostics packages corresponding to problems described in client device diagnostics requests. Session identifiers are generated and returned with diagnostics identifiers to clients which then provide the session identifiers and diagnostics identifiers to a service manager for session initiation. Diagnostics packages are located, retrieved, and provided back to the client by the service manager that invokes a client-side engine to execute diagnostics packages. Results are provided to the diagnostics system which determines additional packages to be executed by the engine during the same diagnostics session. Further, device-specific tokens are acquired by client devices which execute local diagnostic packages and acquire remote diagnostic packages for execution in the same session.
