The invention belongs to the technical field of sugar alcohol compositions, and particularly relates to a sugar alcohol composition containing lutein ester and a preparation method of the sugar alcohol composition. The sugar alcohol composition containing the lutein ester is prepared from the following components: 1.2 to 4.5 parts of gelatin, 30 to 36 parts of crystalline sugar alcohol, 38.6 to 44.2 parts of non-crystalline sugar alcohol, 2 to 6 parts of non-reducing sugar, 1 to 2 parts of glycerol, 1 to 2.3 parts of an emulsifier, 4 to 10 parts of grease, 0.2 to 0.6 part of lutein ester powder, 4 to 8 parts of sugar-free blueberry powder, 0.07 to 1.45 parts of an acidity regulator, 0.6 to 1.1 parts of blueberry essence powder, 2 to 4 parts of concentrated blueberry juice and 49.2 to 57.4 parts of water. The preparation method comprises the following steps: respectively preparing a gelatin solution, a mixture A, a mixture B, a mixture C and syrup for later use; and adding a gelatin solution into the syrup, stirring, sequentially adding the mixture A, the mixture B, the mixture C and the sugar-free blueberry powder, uniformly stirring, cooling, and finally preparing the sugar alcohol composition containing the lutein ester. According to the sugar alcohol composition, the sugar alcohol and other raw materials are reasonably selected and proportioned, and the problems that an existing sugar alcohol composition is not easy to form and prone to water loss, hardening and discoloring are solved.

The invention provides a Fe-Si-Al magnetic powder core and a preparation method and application thereof. The preparation method comprises the following steps: (1) pre-annealing gas-atomized Fe-Si-Al soft magnetic alloy powder; (2) boric acid, metal salt and a solvent are mixed to obtain coating liquid, the pre-annealed magnetically soft alloy powder is added, and coating magnetically soft alloy powder is obtained through stirring; (3) mixing the nano dielectric ceramic powder, attapulgite and a solvent to prepare a suspension, heating and stirring to obtain an inorganic gelatinized insulating coating liquid, and mixing and stirring the coated magnetically soft alloy powder and the inorganic gelatinized insulating coating liquid to obtain double-layer coated magnetically soft alloy powder; (4) mixing and pressing the double-layer coated soft magnetic alloy powder and zinc stearate, and performing high-temperature annealing treatment to obtain the Fe-Si-Al magnetic powder core. The Fe-Si-Al magnetic powder prepared by the preparation method is uniform in insulating layer, high in strength after heat treatment, good in comprehensive performance and relatively low in cost.

This invention discloses an organic electroluminescent device and display device. The organic electroluminescent device includes an anode, a cathode, and at least one light-emitting layer formed between the anode and the cathode. A hole injection layer and a hole transport region are provided between the anode and the light-emitting layer closest to the anode. The hole transport region includes a first hole transport layer and a second hole transport layer with different refractive indices. The first hole transport layer is selected from compounds of Formula 1 or Formula 3, and the second hole transport layer is selected from compounds of Formula 2. This invention's organic electroluminescent device, through improvements in film structure and material matching, ensures both material stability and carrier transport, while simultaneously improving the light field distribution through optimized optical microcavity structure, thus achieving performance enhancement.
