Abstract: The present invention provides a method for preparing a hollow octahedral cuprous oxide, which includes the following steps: (1) mixing a copper chloride solution and a sodium hydroxide solution, and then performing a precipitation reaction to obtain a precipitation solution; and (2) mixing the precipitation solution with glucose and ammonium hydroxide, and then reacting to generate the hollow octahedral cuprous oxide. In the present invention, firstly sodium hydroxide and copper chloride are reacted to generate a copper hydroxide precipitate; then glucose is used to reduce copper ions, and ammonium hydroxide is used to produce graded diffusion dissolution action on octahedral particles, such that the octahedral particles are gradually dissolved into hollow structures. It can be seen from the results of the examples that, the method provided by the present invention can prepare hollow octahedral cuprous oxide with an uniform and pure structure.

Abstract: Techniques for generating quantum light emitters that operate at room temperature and at telecom wavelengths are described. Quantum light emitters of the present disclosure may have various structures. For examples, an SWCNT may chirality of (6,5), (7,5), or (10,3). Quantum light emitters of the present disclosure may be doped with various compounds. In at least some examples, an SWCNT may be doped with an aryl dopant. In at least some examples, the aryl dopant may be an aryl diazonium dopant. Example aryl diazonium dopants include, but are not limited to, 3,5-dichlorobenzenediazonium (Cl2-Dz) and 4-methoxybenzenediazonium (MeO-Dz). Quantum light emitters of the present disclosure may be encapsulated in various materials. In at least some examples, an SWCNT may be encapsulated in a surfactant. An example surfactant is sodium deoxycholate (DOC). In at least some other examples, an SWCNT may be encapsulated in a polymer. In at least some examples, the polymer may be a polyfluorene polymer.

Abstract: A method for preparing a film of aligned rod-like nanostructures or nanotubes comprises preparing a solution that comprises rod-like nanostructures or nanotubes, wherein the rod-like nanostructures or the nanotubes are well-dispersed, and performing vacuum filtration of the solution through a filtration membrane, wherein the vacuum filtration produces a film on the filtration membrane where the rod-like nanostructures or the nanotubes are aligned. The well-dispersed individual rod-like nanostructures or nanotubes may be separately suspended in the solution. The concentration of rod-like nanostructures or nanotubes may be below a threshold value and/or the filtration speed may be as slow as possible. Where a surfactant is utilized to aid dispersion, the surfactant concentration may be below a critical micelle concentration (CMC).
