Photoconductivity of presolvated electrons in ethanol glass at 4 K

Photoconductivity of localized electrons, which are not solvated, in γ-irradiated ethanol glass at 4 K was studied. Photocurrents of 10^?13 A or larger were stably detected in the wavelength range of 900–2200 nm. The wavelength dependence of the photocurrent reveals that pre-solvated electrons probably have no bound excited states.
