“…Fluorescent nanomaterials such as semiconductor quantum dots, nanoparticles, and fluorescent dyes have attracted much attention in recent years. Among them, carbon quantum dots (CQDs) are regarded as novel luminescent materials owing to their excellent advantages such as small particle size, biocompatibility, low toxicity, and simple preparation; they are widely used in fluorescent probes, bioimaging, photocatalysis, and so on .…”

A green method is used to synthesize nitrogen-doped carbon quantum dots (N-CQDs) using dried scindapsus leaves as the carbon source. The average diameter of the N-CQDs varies from 2 to 6 nm. The N-CQDs emit blue light, and the emission wavelength exhibits excitation wavelength dependence. The characteristic peak is found to originate from a N-related state. The surface defects and quantum effects of the CQDs play a strong role in the luminescence process and resulted in the excitation wavelength dependence of the photoluminescence, which is confirmed by changing the solvent to ethanol. This work can encourage the exploration of new carbon sources to synthesize doped CQDs and stimulate investigation of the photoluminescence mechanism of CQDs.

Cu/Co multilayer film was prepared on a Si substrate using a translational jet electrochemical deposition system. A scanning electron microscope, X-ray diffractometer, a 3D surface profilometer, a digital microhardness tester, and a physical property measurement system were used to characterize the surface topography, microtexture, roughness, microhardness, and giant magnetoresistance respectively. It was found that the surface morphology of the multilayer improved and the interface between the Cu and Co layers was well-defined. The roughness and hardness of the multilayer are superior to those of single metal film. The Cu/Co multilayer exhibited an excellent giant magnetoresistive ratio of 50.38%. The giant magnetoresistance increased with the increase in the multilayer cycle number and decreased when the cycle number exceeded 120. The multilayer prepared by this method has high sensitivity to magnetoresistive change and it is easy to control the multilayer's resistance.
