摩擦发光的短波辐射及发光增效摩擦机制研究

Triboluminescence (TL) is induced by deformation and fracture of special class of solids in the process of applying mechanical stress to a friction surface, which reflects the combinative photo- electronic effect in the transition of electrons on the surfacial layer of frictional material by squeezing,impacting and even other stirring factors，so that a potential irradiating application of triboluminescence as phosphoro-light or emergency light can be knowledged according to pioneer study. Blue-violet spectrum as shortwave irradiating light is used to injurious insect control in our agricultural production, therefore a novel and significant research tasks is to boost the shortwave irradiating effect of tribo- luminescence into an useful luminescent light. Based on the requirement of agricultural pest control to shortwave phosphor light, this project suggest to solve the effective emisson of shortwave triboluminescenc as well as its technical realization. First, carry out the dopping fabrication of shortwave triboluminescent coatings made of ZnS:Mn and SrAl2O4:Eu:Dy materials，and test the coating property and its high intensity triboluminescence with blue-violet spectra and even ultroviolet emission；further, explore the friction pair units of continuous triboluminescence and its technical driving mechanism，and innovationally design and fabricate the triboluminescent experiment machine with the friction paires of cage style made from multi-bar and bobbin；another, investigate the tribological principle of tribolumnescenc experiment machine as light unit through exprerimental test and analysis; finally, set up the theory and technology method of effective trimolumnescec with shortwave irradiation as a special light, and build up the application pathway of triboluminescence to agricultural plant protection with physical method.
