摘　　要：用微波吸收相敏技术检测了光谱增感AgBrI T颗粒乳剂的自由光电子时间分辨谱 ,观察到增感样品在染料增感吸收峰位置有明显的光电子信号 ,在AgBrI T颗粒固有吸收带自由光电子衰减时间比未增感样品的衰减时间短。The time-resolved free photoelectron spectra of spectrally sensitized AgBrI-T emulsions were studied by microwave absorption phase-sensitivity detection technique.For the spectrally sensitized emulsions,a distinct signal had been observed in 540nm that was the wavelength peak of spectral sensitization.In the wavelength range in which the AgBrI-T crystal could be exposed,the decay time of the free photoelectron(FDT)of the sensitized emulsions were shorter than that of the unsensitized emulsion.
