Tribo-and Thermo-Luminescence of Aromatic Aldehydes
We found that two typical aromatic aldehydes, 2-furaldehyde and benzaldehyde, sometimes exhibit triboluminescence when these fluid materials at room temperature undergo phase transitions from their glassy phase to crystalline phases under a reduced pressure at low temperature, <I>e. g.</I>, at 77 K. Several optical features thereof have been reported in the present paper. We also often observed characteristic thermal luminescence for a good few 2-furaldehyde solids which were subjected to large and frequent triboluminescence processes.
