Abstract: This present disclosure provides a core-shell quantum dot, a preparation method thereof, and a light-emitting device containing the same. The core of the core-shell quantum dot is CdSeXS(1-X), and the quantum dot shells include a first shell and a second shell, the first shell being selected from one or more of ZnSe, ZnSeYS(1-Y) and Cd(Z)Zn(1-Z)S, the second shell covering the first shell being one of Cd(Z)Zn(1-Z)S and ZnS, the maximum emission peak of the core-shell quantum dot is less than or equal to 480 nm, 0<X<1, 0<Y<1, 0<Z<1. The CdSeXS(1-X) core has a smaller bandgap and a shallower HOMO energy level, making hole injection easier.

Abstract: A resource scheduling method and system, and a computer-readable storage medium are provided. The method comprises: a control instruction inputted by a user (S101) is acquired; on the basis of the control instruction, an intended device (S102) is determined; in the case where the intended device is not able to be started, with regard to each function of the intended device, a constructed knowledge graph is queried for alternative devices associated with the function, the knowledge graph having a plurality of functions stored therein as well as devices associated with the plurality of functions (S103, S105); and a device to be started is determined from all the alternative devices and starting the determined device (S106). In the resource scheduling method, in the case where an intended device specified by a user is not able to be started, alternative devices are appropriately determined.

Abstract: A method for controlling an electrical appliance, and a non-transitory computer-readable storage medium. The control method comprises: receiving a voice control instruction (S101); when the identity of a user who issued the voice control instruction is determined to be a child, acquiring a child knowledge graph (S102); when determined that a control object is a first electrical appliance, determining whether a knowledge expression corresponding to the first electrical appliance exists in the child knowledge graph (S103); if a knowledge expression corresponding to the first electrical appliance doesn't exist in the child knowledge graph, then not responding to the voice control instruction; otherwise, carrying out processing on the voice control instruction according to the knowledge expression corresponding to the first electrical appliance in the child knowledge graph (S104).
