1932 A. L. Hughes & L. A. DuBridge Photoelectr. Phenomena viii. 329 Coblentz studied the photoconductivity of the halides of thallium, lead, and silver.
1974 Encycl. Brit. Macropædia XIII. 817/2 The most outstanding physical property of crystalline selenium is its photoconductivity: on illumination, the electrical conductivity increases more than 1,000-fold.
2001 Proc. National Acad. Sci. U.S.A. 98 14396/1 At high applied electric fields, a peak in the photoconductivity is observed when the sample is pumped at a photon energy just below the onset of the band-to-band π-π* absorption.
