Abstract: | It is shown that acoustic treatment of piezoelectric zinc selenide crystals by exciting strong natural elastic vibrations
can specifically alter their photoelectric and other properties. Irreversible changes in the stressed-strained state of the
crystals under this treatment are responsible for characteristic features in the spectral dependences of the permittivity
ε′(λ) and the dielectric loss coefficient ε′’(λ). These dependences plotted in the form of ε*(λ) diagrams on the complex plane and also the spectrum of natural elastic vibrations can be used to monitor the treatment process.
