Research Abstract

Mechano-luminescence of rocks induced by friction test and tensile test was evaluated. It was observed that the concluded that luminescence intensity of the rocks with large containing quartz was more intense and the peak at 370 nm which corresponds to the second positive band of nitrogen was observed by the rock in nitrogen gas. It was concluded that the mechano-luminescence of rocks was induced by piezoelectric effect and plasma of ambient gas.
