论文摘要
埃德蒙·贝克雷尔（Edmond Becquerel）于1848年发明了第一个彩色摄影过程。他制作的“光色图像”提出了几个问题，其中敏化层的光致变色性质。在这里，我们介绍了根据Becquerel的过程在银板表面或银箔表面产生的敏化层的第一个特征，该过程是xix $^{\ text {tht}} $世纪科学家称为“银氯化银”。它由分散在微米银氯化物基质中的银纳米颗粒构成。因此，它与广泛研究的Ag/AgCl复合材料相似，该复合材料提出了这些光催化剂的新合成途径。敏化层的化学组成已通过互补光谱（EDX，XPS，HAXPES和EXAFS）鉴定，而其形态已通过电子显微镜（SEM和SEM和STEM）进行了研究。这些技术涉及X射线或电子束，这可能会对基于氯化银的敏化层产生影响。因此，本文的很大一部分介绍了对梁效应和减少它们的方式的研究。
Edmond Becquerel invented in 1848 the first colour photographic process. The "photochromatic images" he produced raised several questions, among which the photochromic nature of the sensitized layer. Here, we present the first characterization of the sensitized layer created at the surface of a silver plate or a silver foil according to Becquerel's process, which XIX$^{\text{th}}$ century scientists called "silver photochloride". It is constituted by silver nanoparticles dispersed in a micrometric silver chloride grains matrix. It is thus similar to the widely studied Ag/AgCl composites, which suggests new synthesis routes for these photocatalysts. The chemical composition of the sensitized layer has been identified by complementary spectroscopies (EDX, XPS, HAXPES and EXAFS), while its morphology has been studied by electron microscopies (SEM and STEM). These techniques involve X-ray or electron beams, which can have an impact on the silver chloride-based sensitized layer; a large part of this article hence introduces a study of the beam effects and of the way of reducing them.
