Optical and Electrical Properties of Silver Chloride

Simultaneous measurements of absorption, fluorescence, and photoconductivity have been investigated for AgCl as functions of exciting radiation and temperature. Excitation in the range of 250 to 400 millimicrons with temperatures from -180°C to room temperature were employed. Frequency-sensitive apparatus was used throughout the measurements with the light beam chopped at 37.5 cps. An ac electrometer circuit was employed to measure currents in the range ${10}^{-16\mathrm{}}$ to ${10}^{-11\mathrm{}}$ ampere.
