The embodiment of the invention provides an emergent light side substrate of a mirror display device, a production method thereof and the mirror display device, relates to the technical field of display, and can improve the transmittance of the mirror display device and improve the image display effect. The emergent light side substrate of the mirror display device comprises a substrate, and further comprises a reflecting film arranged on the substrate; the reflecting film is divided into a transmissive zone and a reflective zone; the transmissive zone is micro-sized; the transmissive zone part of the reflecting film is light-transmittable; the reflective zone part of the reflecting film is used for reflecting external light. The emergent light side substrate is applied to the mirror display device.

The invention relates to the technical field of vehicle exterior trims, in particular to a vehicle exterior trim with a fluorescent effect. The formula of the vehicle exterior trim consists of the following ingredients in parts by weight: 100 parts of PMMA or ASA resin, 0.2-0.35 parts of lubricant , 5.5-7.0 parts of toughening agent, 0.15-0.28 parts of transparent black pigment, 2.8-3.5 parts of fluorescent agent, 0.2-1.0 parts of dispersant and 0.4-0.5 parts of antioxidant. The invention also relates to a preparation method of the vehicle exterior decoration with fluorescent effect. After adding transparent black pigment and fluorescent agent to the formula, the vehicle exterior parts prepared by injection molding process can not only appear black to achieve the versatile effect of vehicle models, but also can be used in dim light or dark after absorbing light or other electromagnetic radiation. It emits visible light in an environment that is visible to the human eye, helps drivers and pedestrians identify passing vehicles, and promptly reminds drivers and pedestrians to pay attention to safety, thereby greatly improving the safety of vehicles; the preparation process of the present invention is simple and easy, and is conducive to industrial production .

An underwater quenching method for a thin steel plate, the method comprising: polishing, cleaning, and decontaminating the surface of a substrate; placing the pretreated substrate in a water tank, and completely submerging the upper surface of the substrate in water, and using a wavelength The blue / green laser with a range of 400-600nm scans the surface of the substrate, and at the same time, a side blowing device is used to blow off the water vapor generated in the laser quenching process in time; The rapid rise of the temperature of the workpiece makes the surface temperature of the material rise above the austenite transformation temperature. The heat of the processed part of the thin steel plate is absorbed by the water layer on the upper surface of the thin steel plate. The cooling water absorbs the heat and vaporizes violently, taking away a large amount of heat. The thin steel plate is cooled rapidly, so as to meet the requirements of the thin steel plate to be hard on the outside and tough on the inside, and at the same time reduce the thermal influence on the base part.

The invention discloses a rare-earth-ion-doped Cs2LiLuCl6 microcrystalline glass and a preparation method thereof. The microcrystalline glass is composed of the following components in percentage by mole: 35-45 mol% of P2O5, 10-20 mol% of GeO2, 17-25 mol% of NaF, 6-9 mol% of Lu2O3 and 14-20 mol% of Cs2LiLu(1-x)LnxCl6, wherein x=0.05-0.2, and Ln is Ce<3+>, Eu<3+>, Tb<3+>, Pr<3+> or Nd<3+>. The preparation method comprises the following steps: preparing P2O5-GeO2-NaF-Lu2O3-Cs2LiLu(1-x)LnxCl6 glass by a fusion process, and carrying out heat treatment to obtain the transparent Cs2LiLuCl6 microcrystalline glass. The Cs2LiLuCl6 microcrystalline glass has the advantages of deliquescence resistance, favorable mechanical properties, higher short-wavelength blue-violet light transmission rate, high flare light emission output, favorable energy resolution and the like. The preparation method of the microcrystalline glass is simple and lower in production cost.
