LUMINESCENCE PRODUCED AS A RESULT OF INTENSE ULTRASONIC WAVES

Abstract

The luminescence produced by intense ultrasonic waves in the range 0. 66 to 2 mc was investigated in H2O solutions of CCl4 saturated with A and CO. Observations were also made on ether, Me2CO, MeOH, C6H6, and PhNO2. Results show that luminescence is always accompanied by cavitation and starts at the same energy levels as cavitation. Various H2O solutions show luminescence in the same relative amount as the yield of the chemical reaction caused by intense sound waves; the conclusion was that the phenomenon was chemiluminescence. Of the organic materials studied, only PhNO2 showed luminescence, which may be due to some chemical reaction. An apparent frequency dependence for the intensity of luminescence was observed.
