Embodiment 1

[0054] (1) Firing stress luminous powder

[0055] A high-temperature solid-phase method is used to sinter copper-containing zinc sulfide-based stress luminescent powder. Burning powder parameters: Weigh 400g of zinc sulfide raw material, additives include: copper sulfate powder 0.656g, sodium chloride solid 24g, magnesium chloride solid 40g, dissolve the additive in 200ml deionized water, stir to dissolve; add the additive solution and zinc sulfide raw material fully Mixing; place in an oven to dry, the drying condition is temperature 100°C, time 8h. After drying, it is calcined in a muffle furnace at 1100°C for 3 hours; after the reaction, the powder is quickly taken out, and after cooling at room temperature, the powder is cleaned with high-temperature deionized water, and the upper layer is removed after soaking the powder in deionized water for 30 minutes Liquid, repeated 5 times to remove excess impurities; after cleaning, put it in an oven and dry at 100°C for 4 hours. ...

Abstract

The invention relates to a stress luminescent material as well as preparation and application thereof. The composition comprises a stress luminescent material, nanoparticles and an elastic polymer. The visual sensing device has sensitive visual response to mechanical force stimulation, force-light visual sensing is achieved under the condition that no external power supply exists, and the decoration attractiveness of clothes is improved. And the sensor can be widely applied to the aspects of flexible wearable sensing, medical health monitoring, intelligent traffic warning and the like.

Description

technical field [0001] The invention belongs to the technical field of stress luminescence, and in particular relates to a stress luminescence material and its preparation and application. Background technique [0002] In recent years, with the continuous discovery of new high-performance stress-luminescent materials, these stress-luminescent materials that can convert mechanical energy into light energy have created opportunities to solve practical problems. Potential applications in stress sensing and imaging, structural damage monitoring, wearable lighting, self-powered displays, and mechanical energy harvesting and conversion have attracted increasing attention. These achievements have accelerated the practical process of stress luminescence and pushed the study of stress luminescence to a new height. Stress luminescence in elastic materials can be continuously generated by applying cyclic mechanical loads. Inorganic crystals doped with activators are considered to hav...
