A study of the nucleation and growth processes in the synthesis of colloidal gold
TL;DR: In this paper, a preliminary survey with the electron microscope of various preparations of colloidal gold, a study was made of the process of nucleation and growth in gold colloids, and it was shown that nucleating agents may be identified with reducing agents which form a mixed polymer with chlorauric ion before the reduction to the nucleus takes place.

J. Wiesner,Alexander Wokaun +1 more
TL;DR: In this paper, it was shown that by a suitable combination of birefringence and absorption measurements, the particle dimensions can be uniquely determined by combining the two measurements, and the results were in agreement with recent transmission electron microscope studies which reveal the presence of trigonal and hexagonal platelets.
