EFFECT OF pH ON SPECTRAL SENSITIZATION OF SILVER CHLORIDE
The effect of pH on the spectral sensitization of silver chloride was studied electrochemically. The sensitized photocurrent by rhodamine B decreased with lowering pH of the electrolyte solution, whereas in the case of 1,1′-diethyl-2,2′-quinocyanine chloride, the increase in the sensitized photocurrent was observed. The above fact suggests that H+ existing in the vicinity of the silver chloride surface plays an important role in increasing the sensitized photocurrent.
