Abstract: Disclosed are an ADC (error automatic correction) method and apparatus, an analog-digital conversion circuit and a storage medium. The method comprises: generating at least two preset input voltage signals that respectively form a preset ratio with a reference input voltage signal by means of a reference ratio generation circuit; obtaining, on the basis of a preset conversion rule, a corresponding offset error value and gain error value for ADC correction by means of the preset input voltage signals; and correcting, on the basis of the offset error value and the gain error value, the acquired input voltage signal to be corrected. In this regard, a reference ratio generation circuit generates a preset input voltage signal that forms a preset ratio with a reference input voltage signal, so that the correction of the gain error value and offset error values of various types of ADCs can be met without knowing the specific value of a reference source. Moreover, the correction process of the embodiments is completely automated, without the need for external correction tools and professional correction operations, saving on labor costs and operating hours, and the correction effect is accurate.

Title: Preparation method for iron ion coordinated black phosphorus quantum dot having high stability and strong fluorescence emission
Inventor: JIN HUI
IPC: G01N21/64
Filed: 2020-07-07
Abstract: Disclosed in the present invention is a preparation method for an iron ion coordinated black phosphorus quantum dot Fe@BPQDs having high stability and strong fluorescence emission. In the presence of Fe ions, ultrasonic-assisted solvent thermal treatment is carried out on black phosphorus BP crystals to prepare Fe coordinated few-layer Fe@BP nanosheets; a water-soluble short-chain mercaptan ligand is added, and solvent thermal treatment is carried out on the Fe@BP nanosheets to prepare mercaptan stabilized Fe@BPQDs. Because transition metal M can be spontaneously adsorbed on the surface of BP by means of M-π interaction, lone pair electrons of the BP are passivated, and the BP is more stable in the air and water. A metal phosphide M  x P is formed on the surface of the BP, so that the stability and the optical properties of the Fe@BPQDs are effectively improved. The water-soluble mercaptan ligand is combined with Fe  x P by means of an Fe-S bond, so that functional modification and potential application of the Fe@BPQDs are facilitated, and the Fe@BPQDs can particularly be applied to fluorescence imaging of living cells and living small animals.
