However, there is no description of the particle size of the silver sulfide sol actually obtained, and the particle size distribution is also unclear. Therefore, even with this method, the size and number cannot be controlled.

次に硫化金銀の形成について実施例を挙げる。As described above, it can be seen that by controlling the conditions during particle formation, fine particles with clearly uniform particle size distribution can be formed. Further, the average particle size can be controlled to be smaller by forming particles at a low temperature as in Example 3. In this example, low-molecular gelatin is used because commonly used high-molecular gelatin (molecular weight 100,000 or more) is set at about 30° C., depending on the molecular weight and type. Furthermore, this can also be done by adjusting the supply rate and pH of the reaction solution, as well as the concentrations of various ions. Next, examples will be given regarding the formation of gold and silver sulfide.
