Paper Abstract

In this experiment the microwave absorption and phase-sensitive detection technique was used to detect the time-resolved signal of photoelectrons generated by 35-ps laser pulses in AgCl emulsions uniformly doped with different concentrations of formate ions (HCO2-). According to photoelectron decay signal, the photoelectron decay properties and the trap-capture properties, influencing the efficiency of latent image formation of the cubic AgCl grains, were discussed. The results indicate that when its concentration is 10-5mol/molAg, the formate ions act as hole traps obviously, enhancing the escape of electrons from pair recombination, but when its concentration is more than or less than 10-5mol/molAg, the formate ions may not act as hole traps effectively. We find that the optimal concentration of uniformly doped formate ions which can increase the photoelectron lifetime effectively is 10-5mol/molAg.
