Query: Effects of Sliding Speed on the Intensity of Triboluminescence in Slide
  contact: Experimental Measurements and Theoretical Analyses   Triboluminescence (TL) is the emission of light produced by rubbing or
striking two materials together. Here, the light emission has been observed
from the sliding contact between two disks under dry condition. The effects of
the sliding speed on the intensity of TL have been experimentally investigated.
The results show that the intensity of the emission light increases
significantly with the sliding speed. A theoretical model is also proposed and
an analytical expression is deduced for the intensity of TL in the slide
contact. The theoretical prediction is found consistent with the experimental
results. The present work may be helpful to the understanding of the mechanism
of light emission when friction.
