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.
