A preparation process and LED application of copper nanoclusters (Cu NCs) fluorescent nanoflowers with high quantum yield by dissolving CuIinto dimethyl sulfoxide (DMSO) and then adding glycerol, it self-assembles into Cu NCs s fluorescent nanoflowers. The CuIfluorescent nanoflowers prepared by the invention have outstanding optical properties, a quantum yield up to 64.5%, and can be made into a series of different luminous colors and excellent stability LED only with commercial blue phosphor, such as yellow-green, sky blue, white, wherein according to the mass ratio of 4:5 ratio mix can be prepared white light emission LED. Fluorescent Cu NCs can successfully replace traditional light conversion materials and prepare environmentally friendly LEDs.

A preparation process of atomically precise nine-nuclear silver nanoclusters (Ag-NCs) fluorescent nanotube and its application in the detection of arginine (Arg), the fluorescent nanotube is formed by supramolecular self-assembly of Ag-NCs and peptide (DD-5); the fluorescent nanotube prepared by the present invention has good luminescence performance due to its highly ordered structure, the quantum yield is 8.11%, and the fluorescence lifetime is 6.10 μs; after adding Arg, the highly ordered structure is destroyed, resulting in fluorescent quenching; the preparation method of the Ag-NCs fluorescent nanotube of this invention is simple, the cost is low; at the same time, the detection method is fast and easy to observe.
