Formation of Center of Development on ZnO-Resin Layer by Electrolysis

Abstract

It was previously reported that a small amount of electrodeposited zinc on the photocon ductive zinc oxide-resin layer reduces 2, 3, 5-triphenyltetrazolium chloride (TTC) and phospho molybdic acid (PMo) to 1, 3, 5-triphenylformazan red (TF) and molybdenum blue (MoBlue), respectively. Effects of various factors on the efficiency of the system have been investigated in the present work. The factors studied are kind of electrolyte, it's concentration, the bath voltage, solution temperature, the quantity of electricity and the amount of electrodeposited zinc.
An aqueous solution of 10^-2 mol/l zinc acetate is suitable as the electrolyte. The optimum temperature and bath voltage for electrolysis are 20°C and about 20 V, respectively. The amount of deposited zinc is proportional to the quantity of electricity, and the efficiency is 77% at 10°C. It is estimated from the electricity-exposure relationship that photoconduction of zinc oxide obeys the reciprocity law in the range between 10² and 10⁴ lux sec.
