This invention discloses a polysaccharide-based freshness indicator microsphere, its preparation method, and its application, belonging to the field of intelligent food packaging and quality monitoring technology. The polysaccharide-based freshness indicator microsphere uses xanthan gum and sodium alginate as a composite substrate and is loaded with blueberry anthocyanins. The specific preparation method includes the following steps: First, xanthan gum solution and sodium alginate solution are prepared and mixed to obtain a composite polysaccharide solution; then, the composite polysaccharide solution is dripped into calcium chloride solution using a constant flow injection pump and allowed to solidify by static standing to form hydrogel microspheres; finally, the hydrogel microspheres are immersed in a blueberry anthocyanin solution for loading, and then freeze-dried under vacuum to obtain the polysaccharide-based freshness indicator microspheres. The polysaccharide-based freshness indicator microspheres of this invention exhibit good sphericity, structural stability, and sensitive response, and can produce a significant color response to volatile alkaline substances such as ammonia. They can be used for the visual monitoring of the freshness of black tiger shrimp, especially distinguishing the quality changes of black tiger shrimp from fresh to semi-fresh, and have good practical application value.

This invention belongs to the technical fields of optoelectronic devices, spin optoelectronics, and organic-inorganic hybrid semiconductor materials. Specifically, it relates to a circularly polarized electroluminescent device based on a one-dimensional / three-dimensional perovskite heterostructure and its implementation method. The circularly polarized electroluminescent device includes a substrate, a bottom electrode layer, an electron transport layer, a light-emitting layer, a hole transport layer, and a top electrode stacked sequentially. The light-emitting layer is a one-dimensional / three-dimensional perovskite heterostructure formed in situ by chiral one-dimensional perovskite and three-dimensional perovskite. This invention constructs a one-dimensional / three-dimensional perovskite heterostructure within the light-emitting layer, utilizing the chiral properties of the one-dimensional perovskite to induce lattice distortion in adjacent three-dimensional perovskite at the heterostructure interface. This results in intrinsic structural chirality and excited-state chirality in the three-dimensional perovskite light-emitting region, achieving stable circularly polarized electroluminescence without the need for an external magnetic field or spin injection, thus enabling the device to simultaneously achieve high luminous efficiency and good stability.
