| Abstract Scope |
Triboluminescence, which is light emission by friction and wear, is being considered for application to sensors, security, energy conversion, and so on. In this study, triboluminescence of CaAlSiN3:Eu and AlN:Mn ceramics was investigated. Triboluminescence of these materials intensity increased with an increase in the wear volume because the triboluminescence resulted from the fracture of the materials. In particular AlN :Mn ceramics showed better luminescence than CaAlSiN3:Eu ceramics, and luminescence even without wear. Furthermore, triboluminescence intensity of AlN:Mn increased with a decrease in the oxygen in AlN lattice and the quantity of Mn. |
