Abstract: Some embodiments of the disclosure provide a fluorescent composite particle. In some examples, the fluorescent composite particle includes a fluorescent material having a plurality of fluorescent nanocrystals, and an oxide material. The fluorescent material is densely coated with the oxide material, and a molar ratio of the fluorescent material to the oxide material is 10:1 to 1:100. The fluorescent composite particle has a particle size of 20 nm to 500 nm, a density of 1.8 g/cm3 to 7 g/cm3, and a specific surface area of 8 m2/g to 200 m2/g. According to some embodiments of the present disclosure, the fluorescent composite particle having high stability and small particle size may be provided. Moreover, the present disclosure further provides two preparation methods for obtaining a fluorescent composite particle having a predetermined morphology.

Abstract: The present disclosure provides a docking station and a cleaning system, where the docking station includes: at least one accommodating chamber, and a docking chamber for docking of a self-moving cleaning apparatus; and a height of the docking station is less than 350 mm. The docking station in the embodiments of the present disclosure has a smaller height and can be placed in a low space, improving adaptability of the docking station. Moreover, the integrated box is movable, and if the integrated box is placed in an embedded mode, replacement of consumables is realized by moving the integrated box, without the need to move the docking station out of the embedded space, thereby making the replacement of consumables to be more convenient.
