【摘要】 利用微波吸收介电谱检测技术测量了不同曝光波长下增感乳剂和未增感乳剂的自由光电子衰减曲线, 发现在355nm 和532nm 波长曝光下,乳剂增感之后光电子衰减均变快了。并且在532nm 波长曝光下,与未增感乳剂相比,乳剂增感之后光电子衰减的变化率较大。这主要是因为不同波长曝光下光电子的产生渠道不同, 从而使得355nm 波长曝光下吸附染料只影响光电子的衰减,而对其产生量没有影响；532nm 波长曝光下染料对光电子的产生量及位置和光电子的衰减都会产生影响。更多还原

【Abstract】 The sensitized and unsensitized emulsions are exposed by light with different wavelength. The photoelectron decay carves are measured by microwave absorption and dielectric spectrum detection technology.It is found that the photoelectron decays both become faster after sensitized when the emulsion is exposed by light with 355nm and 532nm wavelength.And under the exposure of 532nm wavelength light,the change extent of photoelectron decay of the sensitized emulsion is lager than that of pure emulsion.The reason is that the source of photoelectron under different exposure wavelength is different,which induce that the dye adsorption only influences the photoelectron decay but does not influence the source of photoelectron under the exposure of 355nm wavelength;while under the exposure of 532nm wavelength the initial number,source place and decay of photoelectron are all influenced by dye adsorption.更多还原
