The application provides a refrigerator, which belongs to the refrigeration technical field and comprises a cabinet, a cabinet door, and an ice maker connected to the cabinet or the cabinet door. The ice maker comprises a first support, an ice tray installed on the first support, and an ice storage box installed on the first support. An ice storage cavity for receiving and storing ice is formed in the ice storage box, and the ice storage cavity is located below the ice tray to receive ice falling from the ice tray. A sterilization device is connected to the first support and located on one side of the ice tray in the length direction. The sterilization device comprises a sterilization light source configured to irradiate the ice storage cavity to sterilize the ice storage cavity and the ice therein. The sterilization device is arranged on one side of the ice tray in the length direction, and the sterilization light source of the sterilization device irradiates the ice storage cavity, thereby sterilizing the surface of the ice block, the inside of the ice block, and the ice storage cavity. The sterilization device can effectively improve the sterilization uniformity of the ice storage cavity and the ice block inside, and ensure the cleanliness of the ice storage cavity and the ice block.

The present invention relates to the technical field of dimming films, and particularly to a dye PDLC composition and a PDLC dimming film. Based on the total weight of the dye PDLC composition being 100%, the dye PDLC composition comprises the following components in percentage by weight: 35-66% of a liquid crystal composition, 3-7% of an anthraquinone-type dichroic dye, 30-60% of a polymer precursor, 0.05-3% of a photoinitiator, and 0.2-1% of a spacer. The polymer precursor comprises an oligomer and an active diluent with a mass ratio of 1:(2-7). The components of the dye PDLC composition provided by the present invention act synergistically, and the PDLC dimming film prepared therefrom has a high off-state haze, a low on-state haze, and a low driving voltage, and at the same time has excellent properties such as light absorption and heat insulation, a wide full-light dimming range, and color tunability.

The application provides a full-spectrum complex-phase fluorescent ceramic and a preparation method and application thereof. 1‑x‑y Sr y AlSiN3:xEu (0 1‑x‑a‑b Y a Gd b )3(Al 1‑c Ga c )5O 12 :xCe (0 12 The short-time ceramic sintering and the faster temperature rising and falling rate in the application effectively slow down the grain growth in the ceramic sintering process, and in the short-time sintering process, the nitride powder forms the oxide phase in situ without causing large decomposition or sintering so as to make it invalid. In short, through the short-time high-temperature pulse sintering, the sintering densification of the complex-phase ceramic is promoted, and the nitride phase is avoided from being oxidized in the long-time high-temperature process to cause the sharp drop of the luminous efficiency.

The application discloses a cellulose-based room-temperature phosphorescent carbon quantum dot coating and a preparation method and application thereof, and belongs to the technical field of room-temperature phosphorescent coatings. The preparation method specifically comprises the following steps: (1) cellulose-based precursor solution preparation; (2) solvothermal carbonization and purification treatment; (3) urea modification treatment; and (4) coating compounding. The application takes natural cellulose as a green precursor, and through solvothermal nitrogen doping of cellulose and urea modification cooperation, in combination with rigid confinement of the waterborne polyurethane emulsion, a carbon quantum dot coating with long service life, color adjustment, and high-efficiency room-temperature phosphorescent performance is prepared. The coating is not only environment-friendly and simple in process, but also has excellent compatibility with a wood-based material, and has good mechanical performance and long-term stability, and can be widely applied to fields of high-end decoration, intelligent packaging and information encryption anti-counterfeiting and the like.
