摘要：

Triboluminescence has been observed in single crystals of MgO, CaO and SrO deformed by compression in a temperature range from 80 to 300 K. It appears to be a new intrinsic effect, independent of impurities or surface conditions and is of three types corresponding to three regions of the stress-strain curve. The nature of the defect emission center is open to speculation, but it is proposed that dislocation induced excitonic transitions adjacent to vacancy clusters produce the emission. © 1979.
