glow in the dark tape electroluminescent principle

One plastic light-emitting light-emitting principle agents are crystalline phosphor or π electron organic coloring substances , they are due to the transition of electrons generated by realglow gravels for sales after excitation . Similar light-emitting materials with photoluminescence , electroluminescence mechanism of general polymer mainly in the electricity, respectively, from the positive and negative injected holes and electrons migrate these two carriers occur in the electric field , which in the polymer exciton complexes into one place , then the occurrence of exciton luminescence decay . Exciton luminescence process can be divided into exciton formation and decay realglow yellow green steps , which injected carriers ( electrons and holes ) through migration within the polymer semiconductor encounter, or the formation of singlet excitons triplet excitons , singlet exciton recombination radiation decay by emitting photons, triplet exciton energy ratio due to its much lower singlet excitons , which decay basic non- radiation. EL wire is extruded layer of the outer conductor luminous light-emitting materials , the insulated conductors realglow blue green copper or high -intensity tightly twisted together. In use, the inner conductor is energized , the outer conductor is grounded, a potential difference exists on such an insulating material , these two carriers migrate in the electric field occur , they are combined into excitons in a polymer , and then the exciton decay occurs and light.
