Zur Pr�fung des photochemischen �quivalentgesetzes an Trockenplatten

Reduction of Silver Halides and the Mechanism of Photographic Development.

“…The production of silver by prolonged exposure to light had been established much earlier and was the subject of numerous studies. Eggert and Xoddack (20,21) found that the amount of photolytic silver followed Einstein's law of photochemical equivalence, so that the number of reduced silver atoms is equal to the number of quanta absorbed. This relation can be found only in the presence of a halogen acceptor.…”

Experimental Study of the relation between intermittent and nonintermittent sector-wheel photographic exposures

“…Applying these principles to the case of an emulsion of finite thickness, we have, in the formation of the image, light absorbed by the silver halide (11), (12); consequently its intensity diminishes as it proceeds through the emulsion layer. With illuminations higher at the surface, but deeper in less than the critical value, a combined type of image (fading and growing) should be formed.…”

Le mécanisme de la formation de l'image latente photographique

“…Enfin, à l'appui de cette théorie viennent les expériences sur le rendement quantique, en particulier celles de Eggert et Nodack [ 13] qui ont trouvé un rendement quantique de la photolyse du bromure d'argent égal à i, tout au moins au début et pour de faibles éclairements en lumière ultraviolette.…”
