摘要： A quantum dot light-emitting device and a manufacturing method therefor, and a display panel. The quantum dot light-emitting device comprises: a quantum dot layer and an electron transport layer adjacent to the quantum dot layer; the electron transport layer comprises a first group, and the quantum dot layer comprises a second group; the first group and the second group each comprise a hydrophilic group. The first group and the second group are combined by means of a hydrogen bond on contact surfaces of the quantum dot layer and the electron transport layer, to enhance an interface interaction force between the quantum dot layer and the electron transport layer, thereby reducing interface defects of the quantum dot layer and the electron transport layer, and improving the electroluminescence performance and stability of the quantum dot device.

摘要： The present disclosure provides a ratiometric fluorescent probe, a preparation method thereof, and an application in detection of hydrogen peroxide. In the present disclosure, MoOx QDs (nanoenzymes) and Co/Zn-MOFs both have catalytic activity, and the large specific surface area and porous structure of Co/Zn-MOFs can provide more binding sites for the contact between nanoenzymes and substrates. Moreover, Co/Zn-MOFs have high catalytic activity similar to natural enzymes. When nanoenzymes with fluorescent properties encounter Co/Zn-MOFs with similar catalytic activity, they will collide with a spark of “synergy catalysis”, and the fusion of the two plays a role of synergy catalysis; in addition, the uniform cavity of Co/Zn-MOFs can provide “hosts” for nanoenzymes, and Co/Zn-MOFs provide “anchors” for MoOx QDs, avoiding the aggregation of MoOx QDs and enhancing the stability of the probe.

摘要： A metamaterial shell architected on a core particle (comprising organic or inorganic material) so as to form a novel class of structurally hierarchical particle that has degrees of freedom in design parameters stemming from effective optical response of the metamaterial shell and from the electromagnetic modes in the core to elicit optical behaviours that are not easily achievable and designable in particles having simpler or smoother geometries.
