摘要： A method for forming CsPbBr 3 perovskite nanocrystals into a two-dimensional (2D) nanosheet includes providing (106) CsPbBr3 perovskite nanocrystals (208); mixing (108) the CsPbBr 3 perovskite nanocrystals (208) into a mixture of a first solvent (210) and a second solvent (212), to form a solution (206) of the CsPbBr 3 perovskite nanocrystals, the first solvent, and the second solvent; and forming (112) an optoelectronic device (200) by patterning the CsPbBr 3 perovskite nanocrystals (208) into a nanosheet (312), between first and second electrodes (220A, 220B). The first solvent (210) is selected to evaporate before the second solvent (212).

摘要： A photodetector (600) for detecting deep ultra-violet light includes a substrate (610); first and second electrodes (603, 605) separated by a channel (607); and colloidal MnO based quantum dots (112) formed in the channel (607). The colloidal MnO based quantum dots are sensitive to ultra-violet light having a wavelength lower than 300 nm.

摘要： 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.
