Uses: Stress luminescence, electroluminescent device fabrication and other scientific experiments.
Storage: electronic drying cabinet, relatively moderate < 30%, normal temperature.
Stress luminescent materials are composed of inorganic luminescent microcrystalline powder. Stress luminescent materials emit light mainly due to the electret effect of microcrystalline luminescent materials under the external action. Of course, microcrystalline luminescent materials can also produce instantaneous visible light radiation when they are elastically deformed or deformed (irrecoverable). When the colloid is mixed with luminescent materials, the moving colloid rubs against the surface of luminescent crystals, resulting in the gradual accumulation of charges to instantly form an excited electron transition state to produce visible light radiation.
Can be used for: elastic sensor, pressure sensor, friction sensor, electrostatic sensor.
Crystal structure: hexagonal phase, cubic phase and mixed phase.
Composition: alkaline earth sulfide (ZnS:Cu)
