摘要： A stable and efficient light-emitting all-inorganic calcium fluoride perovskite quantum dot, a preparation method therefor, and an application thereof. The all-inorganic calcium fluoride perovskite quantum dot is prepared by a simple high-temperature hot injection method, and the prepared all-inorganic calcium fluoride perovskite quantum dot has good dispersibility, uniformity and repeatability. Due to the protection of fluorine ions on a CsPbX 3 quantum dot, the all-inorganic calcium fluoride perovskite quantum dot has stronger fluorescence emission and better stability than a pure CsPbX 3 quantum dot; and the all-inorganic calcium fluoride perovskite quantum dot has a fluorescence quantum yield of about 100% and a fluorescence lifetime that single-exponentially decays, and can still emit dazzling fluorescence after one year. The all-inorganic calcium fluoride perovskite quantum dot can be used as a stable and efficient nano-luminescent material, and has potential application prospects in the fields of photoelectric and photovoltaic devices and the like.

摘要： A light-emitting display device based on special-shaped nLED grains comprises an upper drive electrode substrate, an upper drive electrode, special-shaped nLED grains, a lower drive electrode and a lower drive electrode substrate that are sequentially arranged from top to bottom, and is further provided with an AC drive control module having two ends connected to the upper drive electrode and the lower electrode respectively. The special-shaped nLED grains are nLED grains each comprising a non-planar luminous layer. The drive electrode is isolated from the nLED grains by insulating dielectric layer. In presence of the AC drive signal, the nLED grains are lighted up through electromagnetic coupling. By adoption of special-shaped nLED grains, when a grain sheet is disposed between the electrode substrates, the luminous layer of each nLED grain is always partially parallel to the electrode substrates and perpendicular to an electric field, thus greatly improving electrical coupling efficiency and luminous efficiency.
